The ADC0808, ADC0809 data acquisition component is a
monolithic CMOS device with an 8-bit analog-to-digital converter,
8-channel multiplexer and microprocessor compatible
control logic. The 8-bit A/D converter uses successive approximation
as the conversion technique. The converter features
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.
The device eliminates the need for external zero and full-scale
adjustments. Easy interfacing to microprocessors is provided
by the latched and decoded multiplexer address inputs and
latched TTL TRI-STATE outputs.
