The ADS7822UC is a 12-bit sampling analog-to-digital converter (ADC) from Texas Instruments that uses a successive approximation register (SAR) architecture. It achieves a maximum sampling rate of 200 kS/s and provides a pseudo-differential input with an external reference. The device communicates via an SPI interface.
This ADC is designed for low power consumption, drawing only 1.6 mW at the full 200 kHz sampling rate. At lower conversion rates, power dissipation drops significantly to 0.54 mW at 75 kHz and 0.06 mW at 7.5 kHz. A power-down mode reduces supply current to a maximum of 3 µA. The ADS7822UC operates over a supply voltage range of 2.7V to 5.25V and an input voltage range of 0V to 5.25V. It achieves a typical signal-to-noise ratio (SNR) of 71 dB.
The ADS7822UC is offered in an 8-pin SOIC package (8-SOIC) with dimensions of 4.9 mm x 6 mm, suitable for surface-mount assembly. It is rated for operation over the industrial temperature range of -40°C to 85°C.
