ADS7945SRTER Description

Short technical summary and product information.

The ADS7945SRTER is a high-performance 14-bit, 2 MSPS SAR ADC from Texas Instruments designed for precision data acquisition. It features dual differential input channels with a multiplexed configuration and an external voltage reference. The device operates with an analog supply from 2.7V to 5.25V and a digital supply from 1.65V to 5.25V, drawing a typical power consumption of 10.5 mW at full speed.

 

Electrical performance includes a typical signal-to-noise ratio (SNR) of 84 dB and a maximum integral nonlinearity (INL) of 1.5 LSB, ensuring accurate conversion over the full -40°C to +125°C temperature range. The SPI-compatible serial interface simplifies connection to microcontrollers and digital signal processors.

 

The device is supplied in a compact 16-lead WQFN package measuring 3 mm x 3 mm, suitable for space-constrained applications. The mounting type is surface mount.
