ML145053

10-Bit A/D Converter With

Serial Interface

CMOS

Legacy Device: Motorola MC145053

This ratiometric 10-bit ADC has a serial interface port to provide commu-

nication with MCUs and MPUs. Either a 10- or 16-bit format can be used.

The16-bit format can be one continuous 16-bit stream or two intermittent 8-

bit streams. The converter operates from a single power supply with no exter-

nal trimming required. Reference voltages down to 4.0 V are accommodated.

The ML145053 has an internal clock oscillator to operate the dynamic A/D

conversion sequence and an end-of-conversion (EOC) output.
