Overview
Description
The ADS7957SRHBR is a Texas Instruments 8-channel, 12-bit, multiplexed-input SAR ADC with a SPI-compatible serial interface. It time-multiplexes eight analog inputs (single-ended or differential) into a single 12-bit conversion core, enabling compact multi-channel data acquisition. Key features typically include single-supply operation (2.7–5.5 V), low power, and flexible timing/readout via the serial interface. An external reference is used to set the conversion range. The SRHBR suffix denotes the specific TI packaging/temperature variant of the part. Common applications include data acquisition systems, instrumentation, automotive sensing, and process/control monitoring.
Features
Here are the typical features of the ADS7957SRHBR (TI):
