ADS7947SRTET TI ADC | 16-WQFN (3x3) | 2MSPS, 12-Bit, SAR

Product Overview

The ADS7947SRTET is a high-speed, 12-bit, successive approximation register (SAR) analog-to-digital converter (ADC) from Texas Instruments. It operates at a sampling rate of up to 2 MSPS and features a single-ended input with a wide input voltage range. The device is housed in a compact 16-pin WQFN (3x3 mm) package, making it ideal for space-constrained applications. It offers excellent AC performance with a signal-to-noise ratio (SNR) of 71.5 dB and a spurious-free dynamic range (SFDR) of 85 dB at 100 kHz input frequency. The ADS7947SRTET operates from a single 2.7V to 5.25V supply and consumes only 4.5 mW at 2 MSPS, making it suitable for low-power systems.
