The 0809ADC data acquisition element is a monolithic CMOS device with an 8-bit ADC, 8-channel multiplexer, and microprocessor compatible control logic. The 8-bit Analog to Digital converter utilizes successive approximation as a conversion technique. The converter features a high impedance chopper stabilized comparator, a 256R voltage divider with an analog switch tree, and a successive approximation register. The 8-channel multiplexer can directly access any 8-single-ended analog signals.
Features:
- Easy Interface to All Microprocessors.
- Operates Ratio-metrically, 5 VDC, Analog Span Adjusted Voltage Reference.
- No Zero or Full-Scale Adjust Required.
- 8-Channel Multiplexer with Address Logic.
- 0V to VCC(~6) Input Range.
- Outputs meet TTL Voltage Level Specifications.
- ADC0809 Equivalent to MM74C949-1.
