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.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
