ADC0800 8-Bit A D Converter
General Description
The ADC0800 is an 8-bit monolithic A D converter using P-
channel ion-implanted MOS technology It contains a high
input impedance comparator 256 series resistors and ana-
log switches control logic and output latches Conversion is
performed using a successive approximation technique
where the unknown analog voltage is compared to the re-
sistor tie points using analog switches When the appropri-
ate tie point voltage matches the unknown voltage conver-
sion is complete and the digital outputs contain an 8-bit
complementary binary word corresponding to the unknown
The binary output is TRI-STATE to permit bussing on com-
mon data lines
The ADC0800PD is specified over b55 C to a125 C and
the ADC0800PCD is specified over 0 C to 70 C
