MAX5395开发板套件编程器的评估演示板及套件规格书PDF中文资料

General Description

The MAX5395 single, 256-tap volatile, low-voltage linear taper digital potentiometer offers three end-toend resistance values of 10kΩ, 50kΩ, and 100kΩ. Potentiometer terminals are independent of supply for voltages up to 5.25V with single-supply operation from 1.7V to 5.5V (charge pump enabled). User-controlled shutdown modes allow the H, W, or L terminal to be opened with the wiper position set to zero-code, midcode, full-code, or the value contained in the wiper register. Ultra-low-quiescent supply current (
