LT3950 Demo Board | 60V 1.5A LED Driver with Internal Log-Scale Dimming

Analog Devices Inc.
Demonstration circuit 2788A is a boost LED driver featuring the LT®3950. This demonstration circuit powers a string of LEDs at 330mA. The step-up topology can be used to drive a string of up to 28V of LEDs as assembled. The maximum output voltage capability of the LT3950 is 60V. DC2788A runs from an input voltage range of 6V to 24V as built. It also runs at 2MHz and has the capability to turn on spread spectrum frequency modulation (SSFM) for a frequency range of 2.0MHz to 2.5MHz. Dimming control can be achieved with analog dimming or PWM dimming—either from an external or internally-generated clock source. DC2788A features undervoltage lockout (UVLO) set at 6.6V with a 1.0V hysteresis for turn-on. The UVLO voltage, LED current, output voltage range, switching frequency, brightness control, SSFM, and the topology can all be adjusted with simple modifications to the demonstration circuit. LT3950 is a monolithic 1.5A peak switch current, 60V LED driver. The guaranteed peak switch current rating of the IC is 1.5A and this is important to know when calculating maximum output current at a given LED voltage and input voltage for a boost converter. The LT3950 features SSFM and a well-controlled SW node for low emissions. A frequency range of 200kHz to 2MHz and a high-side PWMTG PWM-dimming MOSFET makes this a very versatile IC for many applications. It can be used for boost, buck-boost mode and buck mode LED driver applications. The PWMTG MOSFET not only provides high PWM dimming ratio capability, but it also serves as a short-circuit protection device. The FAULT flag indicates when there is either a short-circuit or open-LED fault at the output. The demo circuit is designed to be easily reconfigured to suit other applications, including the example schematics in the data sheet. Consult technical support for assistance. High voltage operation, 3V input voltage operation, multiple topologies, small-and-compact size, fault protection, low EMI, and multiple brightness control options make the LT3950 flexible and powerful for compact, noise-sensitive LED driver solutions. The LT3950JMSE featured on this demo circuit is available in a thermally enhanced 16-lead plastic MSOP package. The LT3950 data sheet must be read in conjunction with this demo manual to properly use or modify demo circuit DC2788A.

Analog Devices Inc.
The AD8337 is a low noise, single-ended, linear-in-dB, general-purpose variable gain amplifier (VGA) usable at frequencies from dc to 100 MHz; the ?3 dB bandwidth is 280 MHz. Excellent bandwidth uniformity across the entire gain range and low output-referred noise makes the AD8337 ideal for gain trim applications and for driving high speed analog-to-digital converters (ADCs).Excellent dc characteristics combined with high speed make the AD8337 particularly suited for industrial ultrasound, PET scanners, and video applications. Dual-supply operation enables gain control of negative-going pulses such as generated by photodiodes or photomultiplier tubes.The AD8337 uses the popular and versatile X-AMP? architecture, exclusively from Analog Devices, Inc., with a gain range of 24 dB. The gain control interface provides precise linear-in-dB scaling of 19.7 dB/V, referenced to VCOM.The AD8337 includes an uncommitted operational current-feedback preamplifier (PrA) that operates in inverting or noninverting configurations. Using external resistors, the device can be configured for gains of 6 dB or greater. The AD8337 is characterized by a noninverting PrA gain of 2? using two external 100 ? resistors. The attenuator has a range of 24 dB, and the output amplifier has a fixed gain of 8? (18.06 dB). The lowest nominal gain range is 0 dB to 24 dB and can be shifted up or down by adjusting the preamp gain. Multiple AD8337s can be connected in series for larger gain ranges, and for interstage filtering to suppress noise and distortion, and for nulling offset voltages.The operating temperature range is ?40?C to +85?C, and it is available in an 8-lead, 3 mm ? 3 mm LFCSP.Applications Gain trim PET scanners High performance AGC systems I/Q signal processing Video Industrial and medical ultrasound Radar receivers

EVAL-ADGS1208SDZ

Analog Devices Inc.
The ADGS1208/ADGS1209 are analog multiplexers comprisingeight single channels and four differential channels, respectively. Aserial peripheral interface (SPI) controls the switches. The SPIinterface has robust error detection features, such as cyclicredundancy check (CRC) error detection, invalid read/writeaddress detection, and SCLK count error detection.It is possible to daisy-chain multiple ADGS1208/ADGS1209devices together. Daisy-chain mode enables the configuration ofmultiple devices with a minimal amount of digital lines. TheADGS1208/ADGS1209 can also operate in burst mode todecrease the time between SPI commands.iCMOS? construction ensures ultralow power dissipation,making the devices ideally suited for portable and batterypoweredinstruments.Each switch conducts equally well in both directions when on,and each switch has an input signal range that extends to thesupplies. In the off condition, signal levels up to the suppliesare blocked. The ultralow on capacitance (CON) and exceptionally low chargeinjection (QINJ) of these multiplexers make them ideal solutionsfor data acquisition and sample-and-hold applications, wherelow glitch and fast settling are required.Product Highlights SPI interface removes the need for parallel conversion, logic traces and reduces GPIO channel count. Daisy-chain mode removes additional logic traces when multiple devices are used. CRC error detection, invalid read/write address detection, and SCLK count error detection ensures a robust digital interface. CRC and Error detection capabilities allows for the use of the ADGS1208/ADGS1209 in safety critical systems.Applications Audio and video routing Automatic test equipment Data-acquisition systems Battery-powered systems Sample-and-hold systems Communication systems

AD9523-1/PCBZ

Analog Devices Inc.
The AD9523-1 provides a low power, multi-output, clock distribution function with low jitter performance, along with an on-chip PLL and VCO with two VCO dividers. The on-chip VCO tunes from 2.94 GHz to 3.1 GHz.The AD9523-1 is designed to support the clock requirements for long term evolution (LTE) and multicarrier GSM base station designs. It relies on an external VCXO to provide the reference jitter cleanup to achieve the restrictive low phase noise requirements necessary for acceptable data converter SNR performance.The input receivers, oscillator, and zero delay receiver provide both single-ended and differential operation. When connected to a recovered system reference clock and a VCXO, the device generates 14 low noise outputs with a range of 1 MHz to 1 GHz, and one dedicated buffered output from the input PLL (PLL1). The frequency and phase of one clock output relative to another clock output can be varied by means of a divider phase select function that serves as a jitter-free, coarse timing adjustment in increments that are equal to half the period of the signal coming out of the VCO.An in-package EEPROM can be programmed through the serial interface to store user-defined register settings for power-up and chip reset.APPLICATIONS LTE and multicarrier GSM base stations Wireless and broadband infrastructure Medical instrumentation Clocking high speed ADCs, DACs, DDSs, DDCs, DUCs, MxFEs Low jitter, low phase noise clock distribution Clock generation and translation for SONET, 10Ge, 10G FC, and other 10 Gbps protocols Forward error correction (G.710) High performance wireless transceivers ATE and high performance instrumentation
