DESCRIPTION
The ADC0816, ADC0817 data acquisition component is a monolithic CMOS device with an 8-bit analog-to-digital
converter,16-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 16-channel multiplexer can directly access any one of16-single-ended analog signals, and provides the logic
for additional channel expansion. Signal conditioning of any analog input signal is eased by direct access to the
multiplexer output, and to the input of the 8-bit A/D converter.
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.
The design of the ADC0816, ADC0817 has been optimized by incorporating the most desirable aspects of
several A/D conversion techniques. The ADC0816,ADC0817 offers high speed, high accuracy, minimal
temperature dependence, excellent long-term accuracy and repeatability, and consumes minima lpower. These
features make this device ideally suited to applications from process and machine control to consumer and
automotive applications. For similar performance in an 8-channel, 28-pin, 8-bit A/D converter, see the ADC0808,
ADC0809 data sheet. (See AN-258 for more information.)

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.
