ADS7951SBDBT

Analog To Digital Converters (ADC) Overview

The ADS7951SBDBT is a 12-bit successive approximation register (SAR) analog-to-digital converter (ADC) manufactured by Texas Instruments. It features four single-ended input channels and supports a sampling rate of 1 MSPS. The device operates with an analog supply voltage range of 2.7 V to 5.25 V and a digital supply voltage range of 1.7 V to 5.25 V. It utilizes an external reference voltage of 2.51 V and communicates via an SPI interface. Key performance metrics include a signal-to-noise ratio (SNR) of 70 dB, a signal-to-noise and distortion ratio (SINAD) of 71.3 dB, and differential/integral nonlinearity of +/- 1 LSB. The component consumes 11.5 mW of power and functions within a temperature range of -40°C to +125°C in a TSSOP-30 package.
