SEMICONDUCTOR TECHNICAL DATA  
CMOS  
P SUFFIX  
PLASTIC  
CASE 738  
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.  
DW SUFFIX  
SOG  
CASE 751D  
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.
