ADS7831P TI Analog-to-Digital Converter | 28-DIP | 8-Ch, 12-Bit, 500ksps

Product Overview

The ADS7831P is a high-performance, 12-bit analog-to-digital converter (ADC) from Texas Instruments. It features 8 single-ended or 4 differential input channels, a maximum sampling rate of 500 kSPS, and operates from a single +5V supply. The device includes an internal 2.5V reference, a track/hold amplifier, and a parallel interface. Housed in a 28-pin DIP package, it is ideal for industrial control, data acquisition, and instrumentation systems requiring high accuracy and speed.
