WM5620中文资料欧胜微电子数据手册PDF规格书

描述 Description

WM5620L and WM5620 are quad 8-bit digital to analogue converters (DAC) controlled via a serial interface. Each DACs output voltage range isprogrammable for either x1 or x 2 its reference input voltage, allowing near rail to rail operation for the x 2 output range. Separate high impedance buffered voltage reference inputs are provided for each DAC. WM5620L operates on a single supply voltage of 3 V while WM5620 operates on 5 V.
