ML2280 - Micro Linear

ML2280 Serial I/O 8-Bit A/D Converters

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-todigital converters accuracy specification. The voltage reference can be externally set to any value b.
