Texas Instruments ADS7822EC/250
- Part Number:
- ADS7822EC/250
- Manufacturer:
- Texas Instruments
- Ventron No:
- 3007700-ADS7822EC/250
- Description:
- 12-Bit, 200kSPS Micro Power Sampling Analog-To-Digital Converter
- Datasheet:
- ads7822
Description
The ADS7822 is a 12-bit sampling analog-to-digital (A/D) converter with guaranteed specifications over a 2.7V to 5.25V supply range. It consumes minimal power, even at its full 200kHz sampling rate. At lower conversion rates, the device's high speed allows it to remain in power-down mode for extended periods, resulting in power dissipation below 60µW at 7.5kHz.
The ADS7822 operates from 2.0V to 5V, features a synchronous serial interface, and has a pseudo-differential input. The reference voltage can be set to any level within the range of 50mV to Voc.
Features
200kHz sampling rate
Micropower consumption:
1.6mW at 200kHz
0.54mW at 75kHz
0.06mW at 7.5kHz
Power down: 3μA max

Pseudo-differential input
Serial interface
Applications
Battery-operated systems
Remote data acquisition
Isolated data acquisition
Simultaneous sampling, multichannel systems
