Présentation

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):
- 16-channel multiplexed analog inputs
- 12-bit successive-approximation ADC
- SPI-compatible serial interface
- Internal sample-and-hold
- External reference input (VREF) available
- Programmable channel sequencing and scan modes
- Conversion data can be read in a single frame or streamed
- Data-ready/busy signaling
- Low-power operation with power-down mode
- Wide supply range (single-supply operation)
- Input protection / ESD characteristics suitable for mixed-signal systems
Note: For exact electrical specs, timing, throughput, and pinout, please consult the ADS7957 datasheet.
