SBAS181B – NOVEMBER 2001 - REVISED SEPTEMBER 2003

12-Bit, 8-Channel Sampling

ANALOG-TO-DIGITAL CONVERTER

with I²C^™Interface

DESCRIPTION

FEATURES

ꢀ 8-CHANNEL MULTIPLEXER

ꢀ 50kHz SAMPLING RATE

ꢀ NO MISSING CODES

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.
