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.
