SN55LVCP22-SP Evaluation Module

The ADP1974 is a constant frequency, voltage mode, synchronous, pulse-width modulation (PWM) controller for bidirectional dc-to-dc applications. The ADP1974 is designed for use in battery testing, formation, and conditioning applications with an external, high voltage field effect transistor (FET) half bridge driver, and an external control device such as the AD8450/AD8451. The device operates as a buck converter in battery charge mode and as a boost converter in discharge mode to recycle energy to the input bus.The ADP1974 high voltage VIN supply pin can withstand a maximum operating voltage of 60 V and reduces the need for additional system supply voltages. The ADP1974 has integrated features such as precision enable, internal and external synchronization control with programmable phase shift, programmable maximum duty cycle, dead time control, and peak hiccup current-limit protection. Additional protection features include soft start to limit input inrush current during startup, precision enable, and thermal shutdown (TSD). The ADP1974 also has a COMP pin to provide external control of the PWM duty cycle and a FAULT pin that can disable the DH and DL outputs. These functions are compatible with the AD8450/AD8451 analog front-end (AFE) error amplifiers.The ADP1974 is available in a 16-lead TSSOP package and is pin compatible with the ADP1972.Applications Single and multicell battery formation and testing?

The ADP1765 is a low noise, low dropout (LDO) linear regulator. It is designed to operate from a single input supply with an input voltage as low as 1.10 V without the requirement of an external bias supply to increase efficiency and provide up to 5 A of output current (IOUT).The low 59 mV typical dropout voltage at a 5 A load allows the ADP1765 to operate with a small headroom while maintaining regulation and providing better efficiency.The ADP1765 is optimized for stable operation with small 22 ?F ceramic output capacitors. The ADP1765 delivers optimal transient performance with minimal printed circuit board (PCB) area.The ADP1765 is available in fixed output voltages ranging from 0.55 V to 1.5 V. The output voltage (VOUT) of the adjustable output model can be set from 0.5 V to 1.5 V through an external resistor connected between VADJ and ground.The ADP1765 has an externally programmable soft start time by connecting a capacitor to the SS pin. Short-circuit and thermal overload protection circuits prevent damage in adverse conditions. The ADP1765 is available in a small, 16-lead LFCSP package for the smallest footprint solution to meet a variety of applications.Applications Regulation to noise sensitive applications such as radio frequency (RF) transceivers, analog-to-digital converter (ADC) and digital-to-analog converter (DAC) circuits, phase-locked loops (PLLs), voltage controlled oscillators (VCOs) and clocking integrated circuits Field-programmable gate array (FPGA) and digital signal processor (DSP) supplies Medical and healthcare Industrial and instrumentation

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
