DESCRIPTION
The ADS7828 is a single-supply, low-power, 12-bit data
acquisition device that features a serial I²C interface and an
8-channel multiplexer. The Analog-to-Digital (A/D) converter
features a sample-and-hold amplifier and internal,
asynchronous clock. The combination of an I²C serial,
2-wire interface and micropower consumption makes the
ADS7828 ideal for applications requiring the A/D converter to
be close to the input source in remote locations and for
applications requiring isolation. The ADS7828 is available in
a TSSOP-16 package.
