ADS7863IDBQ

Analog To Digital Converters (ADC) Overview

The ADS7863IDBQ is a dual-channel, 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It supports simultaneous sampling at rates up to 2 MSPS and features an SPI-compatible serial interface. The device accommodates 4 or 6 input channels via internal multiplexers and operates on a single supply voltage ranging from 2.7 V to 5.5 V for both analog and digital domains. Key performance metrics include a signal-to-noise ratio of 71.5 dB, differential nonlinearity of ±1 LSB, and integral nonlinearity of ±1.25 LSB. It functions within a temperature range of -40°C to +85°C and is housed in a 28-pin SSOP package.
