This user guide describes the EVAL-AD5273DBZ evaluation board for evaluating the AD5273, a single channel, 64-position, one-time programmable (OTP) memory digital potentiometer that employs fuse link technology to achieve memory retention of resistance settings. The on-board socket allows the user to easily replace the device for reprogramming of the OTP memory. The AD5273 supports single-supply 2.7 V to 5.5 V operation, making the device suited for battery-powered applications and many other applications with superior low temperature coefficient performance. In addition, the AD5273 uses a versatile I2C serial interface that operates in fast mode.
The document provides a user guide for the EVAL-AD5273DBZ evaluation board designed to evaluate the AD5273 single-channel, 64-position, one-time programmable (OTP) memory digital potentiometer. The kit includes the daughter board, a low voltage DigiPOT motherboard (EVAL-MB-LV-SDZ), and software for PC control via a separately purchased system demonstration platform.
The device supports single-supply operation from 2.7 V to 5.5 V.
The device uses a versatile I2C serial interface that operates in fast mode, allowing speeds of up to 400 kHz.
The software is compatible with Windows XP, Windows Vista, and Windows 7 (both 32 bits and 64 bits).
