The LTC1844 Series are low noise VLDO? (very low dropout) linear regulators designed for low power/portable applications. These regulators can operate from input voltages as low as 1.6V. Typical output noise is only 30?VRMS and typical dropout for the LTC1844-3.3 is just 90mV at the maximum load current of 150mA, reducing to 30mV at 50mA.The internal P-channel MOSFET pass transistor requires no base current, allowing the device to draw only 35?A during normal operation, independent of the dropout voltage and load current. The quiescent current falls to a negligible 10nA during shutdown.Other features include high output voltage accuracy, excellent transient response, stability with ultralow ESR ceramic capacitors as small as 1?F, reverse-battery and reverse-current protection, short-circuit and thermal overload protection and output current limiting.The LTC1844 regulators are available in a low profile (1mm) SOT-23 (ThinSOT?) package.Applications Portable Instruments and Battery-Powered Systems Bluetooth/802.11 Cards Cellular Phones PDAs and Notebook Computers

The LTC2344-16 is a 16-bit, low noise 4-channel simulta- neous sampling successive approximation register (SAR) ADC with differential, wide common mode range inputs. Operating from a 5V supply and using the internal reference and buffer, each channel of this SoftSpan? ADC can be independently configured on a conversion-by-conversion basis to accept ?4.096V, 0V to 4.096V, ?2.048V, or 0V to 2.048V signals. Individual channels may also be disabled to increase throughput on the remaining channels.The wide input common mode range and 102dB CMRR of the LTC2344-16 analog inputs allow the ADC to directly digitize a variety of signals, simplifying signal chain design. This input signal flexibility, combined with ?1.25LSB INL, no missing codes at 16 bits, and 93.4dB SNR, makes the LTC2344-16 an ideal choice for many applications requiring wide dynamic range.The LTC2344-16 supports pin-selectable SPI CMOS (1.8V to 5V) and LVDS serial interfaces. Between one and four lanes of data output may be employed in CMOS mode, allowing the user to optimize bus width and throughput.Applications Programmable Logic Controllers Industrial Process Control Medical Imaging High Speed Data Acquisition

The LTC1772 is a constant frequency current mode step-down DC/DC controller providing excellent AC and DC load and line regulation. The device incorporates an accurate undervoltage lockout feature that shuts down the LTC1772 when the input voltage falls below 2.0V.The LTC1772 provides a ?2.5% output voltage accuracy and consumes only 270?A of quiescent current. For applications where efficiency is a prime consideration, the LTC1772 is configured for Burst Mode operation, which enhances efficiency at low output current. To further maximize the life of a battery source, the external P-channel MOSFET is turned on continuously in dropout (100% duty cycle).In shutdown, the device draws a mere 8?A. High constant operating frequency of 550kHz allows the use of a small external inductor.The LTC1772 is available in a small footprint 6-lead SOT-23.

The EVAL-ADF4XXX is a USB to parallel port adaptor board which allows control of older PLL evaluation boards using a standard USB port. The evaluation board kit comes with a USB cable and the adaptor PCB board. The board contains a USB microcontroller which converts the USB data to lower speed serial data which can be used to control the PLL boards directly. The board also has a USB connector and 25-pin D-connector. The parallel port cable that ships with the older PLL evaluation boards should be connected to the 25-pin D-connector. The USB port should be connected to your pc using the USB cable provided. USB drivers for the board are provided on the standard PLL evaluation board CD. Please install the ADI evaluation board software before plugging in the USB board.

Demonstration circuit 2616A-D features a polyphase design using the LTM4647EY, a 30A high efficiency, switch mode step-down power µModule regulator. The input voltage range is from 6V to 15V. To use DC2616A-D for input voltage range from 4.7V to 6V, connect INTVCC to SVIN (change R22, R42, R55, R68 from OPT to 0Ω), DRVCC to VIN (change R21, R38, R52, R65 from 0Ω to OPT, R2, R39, R53, R66 from OPT to 0Ω). The output voltage range is 0.6V to 1.8V. The DC2616A-D can deliver a nominal 120A output current with four LTM4647 modules in parallel. As explained in the data sheet, output current derating is necessary for certain VIN, VOUT, and thermal conditions. The board operates in continuous conduction mode in heavy load conditions. For high efficiency at low load currents, the MODE_PLLIN jumper selects pulseskipping mode for noise sensitive applications or burst mode operation in less noise sensitive applications. The MODE_PLLIN pin also allows the LTM4647 to synchronize to an external clock signal. The phase shift between two adjacent phases is 90 degrees. DC2616A-D has the option of choosing both internal and external compensation circuit for LTM4647. The LTM4647 data sheet must be read in conjunction with this demo manual prior to working on or modifying demo circuit DC2616A-D.
