ML145051
10-Bit A/D Converter
with Serial Interface - CMOS
Legacy Device: Motorola MC145050, MC145051
These ratio metric 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 accommodated.
The ML145050 has the same pin out as the 8-bit ML145040 which
allows an external clock (ADCLK) to operate the dynamic A/D con-
version sequence. The ML145051 has the same pin out as the 8-bit
ML145041 which has an internal clock oscillator and an end-of-con-
version (EOC) output.
