Description

ADS7957SRHBR is an Analog Devices multi-channel, multiplexed ADC in the ADS7957 family. It’s a successive-approximation (SAR) ADC with an internal input multiplexer and a serial SPI-like interface, allowing a microcontroller to digitize multiple analog signals through one device.
Key points:
- Multichannel: supports several inputs via multiplexing
- Architecture: SAR ADC with a sample/hold and fast conversion
- Interface: SPI-compatible (read/write via CS, CLK, DOUT, DIN)
- Packaging: RoHS-compliant variant (suffix SRHBR indicates a specific lead-free/package option; check datasheet for exact package)
- Features typical for data acquisition: low power, configurable data rate, input reference options, and power-down modes
Common applications:
- Data acquisition systems, sensor arrays, instrumentation, process and motor control, industrial automation
For precise specs (number of channels, input ranges, conversion rate, reference requirements, and exact package details), refer to the current ADS7957SRHBR datasheet.

Features

Here are the main features of the ADS7957SRHBR (datasheet highlights):
- 8-channel, 12-bit analog-to-digital converter
- Multiplexed inputs (single-ended or pseudo-differential)
- SPI-compatible serial interface for microcontroller communication
- Internal sample-and-hold with fast channel switching
- External reference input for flexible full-scale range
- Single-supply operation; suitable for low-voltage systems
- Low-power operation with standby/low-power modes
- Industrial temperature range support
- Available in SRHBR package (lead-free, surface-mount)

Package

ADS7957SRHBR is in a 16‑pin RoHS Pb‑free small outline package (TSSOP-16).

Pinout

- Pin count: 16 pins (MSOP-16/TSSOP-16 package variants such as SRHBR).
- Function: Multichannel analog-to-digital converter with a serial (SPI-compatible) interface and an input multiplexer for sampling multiple analog signals.
