DESCRIPTION
The ADS7830 is a single-supply, low-power, 8-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 ADS7830 ideal
for applications requiring the A/D converter to be
close to the input source in remote locations and for
applications requiring isolation. The ADS7830 is
available in a TSSOP-16 package.
