描述

The SGM58031 is precision analog-to-digital converter (ADC) with 16 bits of resolution. The SGM58031 is designed with precision, low power, and ease of implementation. The SGM58031 features an on-chip reference and oscillator. Data are transferred via an I2C-compatible serial interface; four I2C slave addresses can be selected. The SGM58031 operates from a single power supply ranging from 3V to 5.5V.

The SGM58031 can perform conversions at rates up to 960 samples per second (SPS). An on-chip PGA is available on the SGM58031 that offers input ranges from the supply to as low as ±256mV, allowing both large and small signals to be measured with high resolution. The SGM58031 also features an input multiplexer (MUX) that provides two differential or four single-ended inputs.

The SGM58031 operates either in continuous conversion mode or a single-shot mode that automatically powers down after a conversion and greatly reduces current consumption during idle periods.

The SGM58031 is available in Green MSOP-10 and TDFN-3×3-10L packages and it is specified from -40℃ to +125℃.
