GENERAL DESCRIPTION

The ML2281 family are 8-bit successive approximation A/D converters with serial I/O and configurable input multiplexers with up to 8 input channels.

All errors of the sample-and-hold, incorporated on the ML2281 family are accounted for in the analog-to-digital converters accuracy specification.
