ADS7870EA Description

Short technical summary and product information.

The ADS7870EA is a 12-bit Data Acquisition System (DAS) from Texas Instruments, integrating a SAR ADC, 8-channel multiplexer, programmable gain amplifier (PGA), and internal reference in a single 28-SSOP package. It operates from a 2.7V to 5.5V single supply and provides a sampling rate of 52 kSPS. The device supports both differential and single-ended inputs, configurable up to 4 differential or 8 single-ended channels via the multiplexer.

 

The PGA offers gains of 1, 2, 4, 5, 8, 10, 16, and 20 V/V, allowing signal conditioning for a wide range of sensor outputs. The internal reference can be set to 1.15V, 2.048V, or 2.5V, or an external reference can be used. The serial interface is SPI-compatible up to 20 MHz, and additional features include an oscillator, programmable binary/two's complement output, and 4-bit digital I/O.

 

Housed in a surface-mount 28-SSOP package (5.30mm width), the ADS7870EA is rated for industrial temperature range (-40°C to +85°C). Typical applications include portable battery-powered systems, low-power instrumentation, control systems, and smart sensor interfaces.
