Product introduction

The MS7705/MS7706 is an analog-to-digital converter for low-frequency measurements. Ituses Σ-Δ conversion technology to achieve 16-bit no missing codes output.Operating voltage range: 2.7V-3.3V or 4.75V-5.25V. The MS7705 has 2fully differential analog input channels; the MS7706 has 3 pseudo-differential inputchannels.

The MS7705/MS7706 is ideal for smart, microcontroller-based, or DSP-basedsystems. It can set gain, signal polarity, and output rate through the serial interface.It also supports self-calibration and system calibration to eliminate system gainand offset errors. CMOS technology ensures very low power consumption, with typicalpower consumption of 20μW in standby mode.
