ADC0844/ADC0848

8-Bit µP Compatible A/D Converters with Multiplexer

Options

General Description

The ADC0844 and ADC0848 are CMOS 8-bit successive ap-

proximation A/D converters with versatile analog input multi-

plexers. The 4-channel or 8-channel multiplexers can be

software

configured

for

single-ended,

differential

or

pseudo-differential modes of operation.

The differential mode provides low frequency input common

mode rejection and allows offsetting the analog range of the

converter. In addition, the A/D’s reference can be adjusted

enabling the conversion of reduced analog ranges with 8-bit

resolution.

The A/Ds are designed to operate from the control bus of a

wide variety of microprocessors. TRI-STATE® output latches

that directly drive the data bus permit the A/Ds to be config-

ured as memory locations or I/O devices to the microproces-

sor with no interface logic necessary.
