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 accommodated. 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. 11 Analog Input Channels with Internal Sample-and-Hold Operating Temperature Range: 40 to 125 C Successive Approximation Conversion Time: MC145050 -- 21 s (with 2.1 MHz ADCLK) MC145051 -- 44 s Maximum
