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 munication 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 8bit streams. The converter operates from a single power supply with no external trimming required. Reference voltages down to 4.0 V are acmodated. The ML145053 has an internal clock oscillator to operate the dynamic A/D conversion sequence and an end-of-conversion (EOC) output.
