This user guide describes the evaluation board for evaluating the AD5171, a single-channel, 64-position, one-time programmable (OTP) memory digital potentiometer that uses 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 AD5171 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 AD5171 uses a versatile I2C serial interface that operates in fast mode.
This user guide describes the EVAL-AD5171DBZ evaluation board, designed for evaluating the AD5171 single-channel, 64-position, one-time programmable (OTP) memory digital potentiometer. The board operates in conjunction with the low voltage digiPOT motherboard (EVAL-MB-LV-SDZ) and supports various test circuits including DAC, AC signal attenuation, and signal amplification configurations.
