Product Introduction

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

MS7705/MS7706 is very suitable for smart, microcontroller-based, orDSP-based systems. It can set gain, signal polarity, andOutput rate. It can also perform self-calibration and system calibration to eliminate system gainand offset errors. CMOS process ensures very low power consumption, in standby modetypical power consumption is 20μW.
