ADC0844/ADC0848 8-Bit 碌P Compatible A/D Converters with Multiplexer Options
June 1999
ADC0844/ADC0848
8-Bit 碌P 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鈥檚 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
庐
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.
