ADC0809 - 8-bit Analog to Converter ADC IC Q7 C4

The ADC0809 data acquisition component is based on the monolithic CMOS with an 8-bit analog-to-digital converter, 8-channel multiplexer and microprocessor compatible control logic. These 0809 converters feature a high impedance chopper stabilized comparator, a 256R voltage divider with analog switch tree and a successive approximation register. The 8-channel multiplexer can directly access any of 8-single-ended analog signals.

Input ranges from 0V to the input Vcc, could run through a single supply with 5V, has very low power operations limited to 15mW and the conversion Time is as fast as 100us.
