ADS7947SRTET Description

Short technical summary and product information.

The ADS7947SRTET is a 12-bit successive approximation register (SAR) analog-to-digital converter (ADC) from Texas Instruments. It supports a maximum sampling rate of 2 MSPS and has two input channels configurable as pseudo-differential or single-ended. The device uses an external reference and communicates via an SPI-compatible serial interface.

 

The ADC operates with an analog supply voltage from 2.7 V to 5.5 V and a digital supply from 1.65 V to 5.5 V. The input voltage range is 0 V to 5.5 V. Typical power consumption is 7.5 mW at 2 MSPS. It provides a typical signal-to-noise ratio of 73 dB and a maximum integral non-linearity of 1 LSB.

 

The ADS7947SRTET is housed in a 16-pin WFQFN exposed pad package (3 mm x 3 mm) and is designed for surface mount mounting. It operates over an extended temperature range of -40°C to +125°C.
