GENERAL DESCRIPTION

The ML2280 and ML2283 are 8-bit successive approximation A/D converters with serial I/O and configurable input multiplexers with up to 4 input channels.

All errors of the sample-and-hold incorporated on the ML2280 and ML2283 are accounted for in the analog-to-digital converters accuracy specification.

FEATURES

■ Conversion time: 6µs
