ADS7822E/250 Description

Short technical summary and product information.

The ADS7822E/250 is a 12-bit successive approximation register (SAR) analog-to-digital converter from Texas Instruments. It offers a maximum sampling rate of 200 kilosamples per second (ksps) and accepts a single input channel configured as pseudo-differential or single-ended. The device requires an external reference and operates from analog and digital supply voltages of 4.75V to 5.25V, with a total supply range of 2.7V to 5.25V.

 

Typical power consumption is only 1.6mW when sampling at 200kHz, and drops to less than 60µW at 7.5kHz due to an automatic power-down mode. The signal-to-noise ratio is 71 dB. The SPI serial interface enables simple connection to microcontrollers and digital signal processors.

 

The converter is housed in a surface-mount 8-VSSOP package (3mm × 4.9mm) and is rated for operation from -40°C to 85°C. Typical applications include battery-operated systems, remote data acquisition, isolated data acquisition, and multichannel simultaneous sampling systems.
