ADS7825UB

Analog To Digital Converters (ADC) Overview

The ADS7825UB is a 16-bit, 4-channel successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates with single-ended inputs and supports both parallel and serial interfaces. The device functions within an analog and digital supply voltage range of 4.75 V to 5.25 V, achieving a sampling rate of 40 kS/s. Key performance metrics include a signal-to-noise ratio of 83 dB, differential nonlinearity of ±1 LSB, and integral nonlinearity of ±3 LSB. It features over-voltage protection and consumes 50 mW of power. The component is housed in a SOIC-28 package and operates across a temperature range of -40°C to +85°C.
