Demonstration circuit 1286A is DC/DC boost converter featuring the LTC3862EGN/-1 constant frequency current mode boost controllers. The DC1286A-A (LTC3862) operates over 5V to 36V input and provides 2A-5A of output current at 48V output. The DC1286A-B (LTC3862-1, higher VIN min and higher gate drive) operates over 8V to 36V input and provides 3A-5A of output current at 48V output. The 200kHz constant frequency operation results in small and efficient circuit. The converter provides high output voltage accuracy (typically ±3%) over wide load range with no minimum load requirement. The demonstration circuit can be easily modified to generate different output voltages.

Demonstration circuit 1317A-G is an isolated input to high current output 1/8th brick footprint synchronous forward converter featuring the LT1952 switching controller with Active Reset circuit. The Active Reset circuit can improve the efficiency in wide input voltage applications. Also, the Active Reset allows the implementation of self-driven synchronous secondary rectifiers in some applications. The DC1317A-G converts an isolated 9V to 36V input to 12V at 5A of output current.

Demonstration circuit 1327B is a 4-Channel 80mA LED Driver with +/-1.5% Current Matching featuring the LT3599. The LT3599 is a step-up DC/DC converter designed to drive up to 4-strings of LEDs at up to 120mA per string, and with an output voltage up to 44V. The LED strings are connected to internal current sources where the current level is set with an external resistor. Each string can have up to 10 white LEDs. Paralleling of strings is allowed. The LT3599 runs from a 3.1V to 5.5V power supply, and the step-up converter is powered from an 8V to 16 voltage supply, though higher voltages up to 40V may be acceptable depending on the circuit requirements.

The LTC2631 is a family of 12-, 10-, and 8-bit voltage-output DACs with an integrated, high accuracy, low-drift reference in an 8-lead TSOT-23 package. It has a rail-to-rail output buffer that is guaranteed monotonic.The LTC2631-L has a full-scale output of 2.5V, and operates from a single 2.7V to 5.5V supply. The LTC2631-H has a full-scale output of 4.096V, and operates from a 4.5V to 5.5V supply. A 10ppm/?C reference output is available at the REF pin.Each DAC can also operate in External Reference mode, in which a voltage supplied to the REF pin sets the fullscale output.The LTC2631 DACs use a 2-wire, I2C-compatible serial interface. The LTC2631 operates in both the standard mode (clock rate of 100kHz) and the fast mode (clock rate of 400kHz).The LTC2631 incorporates a power-on reset circuit.

The AD9680 is a dual, 14-bit, 1.25 GSPS/1 GSPS/820 MSPS/500 MSPS analog-to-digital converter (ADC). The device has an on-chip buffer and sample-and-hold circuit designed for low power, small size, and ease of use. This device is designed for sampling wide bandwidth analog signals of up to 2 GHz. The AD9680 is optimized for wide input bandwidth, high sampling rate, excellent linearity, and low power in a small package.The dual ADC cores feature a multistage, differential pipelined architecture with integrated output error correction logic. Each ADC features wide bandwidth inputs supporting a variety of user-selectable input ranges. An integrated voltage reference eases design considerations.The analog input and clock signals are differential inputs. Each ADC data output is internally connected to two digital down-converters (DDCs). Each DDC consists of up to five cascaded signal processing stages: a 12-bit frequency translator (NCO), and four half-band decimation filters. The DDCs are bypassed by default.In addition to the DDC blocks, the AD9680 has several functions that simplify the automatic gain control (AGC) function in the communications receiver. The programmable threshold detector allows monitoring of the incoming signal power using the fast detect output bits of the ADC. If the input signal level exceeds the programmable threshold, the fast detect indicator goes high. Because this threshold indicator has low latency, the user can quickly turn down the system gain to avoid an overrange condition at the ADC input.Users can configure the Subclass 1 JESD204B-based high speed serialized output in a variety of one-, two-, or four-lane configurations, depending on the DDC configuration and the acceptable lane rate of the receiving logic device. Multiple device synchronization is supported through the SYSREF? and SYNCINB? input pins.The AD9680 has flexible power-down options that allow significant power savings when desired. All of these features can be programmed using a 1.8 V to 3.3 V capable, 3-wire SPI.The AD9680 is available in a Pb-free, 64-lead LFCSP and is specified over the ?40?C to +85?C industrial temperature range. This product is protected by a U.S. patent.PRODUCT HIGHLIGHTS Wide full power bandwidth supports IF sampling of signals up to 2 GHz.
