ADS7825PG4

Analog To Digital Converters (ADC) Overview

The ADS7825PG4 is a four-channel, 16-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates with single-ended inputs and supports both parallel and serial digital interfaces. The device functions within an analog and digital supply voltage range of 4.75 V to 5.25 V, consuming 50 mW of power. It achieves a sampling rate of 40 kS/s with a signal-to-noise ratio of 83 dB. Differential nonlinearity is specified at +/- 1 LSB, while integral nonlinearity is +/- 3 LSB. The component is housed in a 28-pin SOIC package and operates between -40°C and +85°C.
