ADS7834P

Analog To Digital Converters (ADC) Overview

The ADS7834P is a 12-bit successive approximation register (SAR) analog-to-digital converter (ADC) manufactured by Texas Instruments. It features a single differential input channel and operates with an SPI-compatible serial interface. The device supports sampling rates up to 500 kS/s while maintaining low power consumption, typically 11 mW at full speed. It requires dual power supplies ranging from 4.75 V to 5.25 V for both analog and digital sections. Key performance metrics include a signal-to-noise ratio of 72 dB, differential nonlinearity of ±0.8 LSB, and integral nonlinearity of ±2 LSB. The component is housed in a DIP-16 package and functions within a temperature range of -40°C to +85°C.
