DESCRIPTION
The ADS7823 is a single-supply, low-power, 12-bit data
acquisition device that features a serial I
2
C interface. The
Analog-to-Digital (A/D) converter features a sample-and-
hold amplifier and internal, asynchronous clock. The combi-
nation of an I
2
C serial two-wire interface and micropower
consumption makes the ADS7823 ideal for applications
requiring the A/D converter to be close to the input source in
remote locations and for applications requiring isolation. The
ADS7823 is available in an MSOP-8 package.
