CMOS
These ratiometric 10-bit ADCs have serial interface ports to provide
communication with MCUs and MPUs. Either a 10- or 16-bit format can be
used The 16-bit format can be one continuous 16-bit stream or two intermittent
8-bit streams. The converters operate from a single power supply with no
external trimming required. Reference voltages down to 4.0 V are accommo-
dated.
The MC145050 has the same pin out as the 8-bit MC145040 which allows an
external clock (ADCLK) to operate the dynamic A/D conversion sequence. The
MC145051 has the same pin out as the 8-bit MC145041 which has an internal
clock oscillator and an end-of-conversion (EOC) output.
