ADS7279IPWRG4

Analog To Digital Converters (ADC) Overview

The ADS7279IPWRG4 is a low-power, 14-bit successive approximation register (SAR) analog-to-digital converter (ADC) manufactured by Texas Instruments. It features a single-ended input configuration and supports a sampling rate of 1 MS/s. The device operates with an analog supply voltage of 5 V and a digital supply voltage of 3.3 V. Key performance metrics include a signal-to-noise ratio (SNR) of 85.9 dB and a signal-to-noise and distortion ratio (SINAD) of 85.7 dB. Differential nonlinearity (DNL) and integral nonlinearity (INL) are both specified at +/- 1 LSB. The component is housed in a TSSOP-16 package and functions within a temperature range of -40°C to +85°C.
