FEATURES  
DESCRIPTION  
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

microprocessors is provided by the latched and  
decoded multiplexer address inputs and latched TTL  
TRI-STATE outputs.  
Resolution: 8 Bits  
Total Unadjusted Error: ±½ LSB and ±1 LSB  
Single Supply: 5 VDC  
The design of the ADC0808, ADC0809 has been  
optimized by incorporating the most desirable aspects  
of several A/D conversion techniques. The ADC0808,  
ADC0809 offers high speed, high accuracy, minimal  
temperature dependence, excellent long-term  
accuracy and repeatability, and consumes minimal  
power. These features make this device ideally suited  
to applications from process and machine control to  
consumer and automotive applications. For 16-  
channel multiplexer with common output (sample/hold  
port) see ADC0816 data sheet. (See AN-247  
(Literature Number SNOA595) for more information.)  
Low Power: 15 mW  
Conversion Time: 100 μs
