DESCRIPTION

Standard, Fast, and High-Speed

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.

● LOW POWER:

180µW (Standard Mode)

300µW (High-Speed Mode)

675µW (Fast Mode)

● DIRECT PIN COMPATIBLE WITH ADS7828

● TSSOP-16 PACKAGE
