ADC0801/ADC0802/ADC0803/ADC0804/ADC0805  
8-Bit µP Compatible A/D Converters  
n Differential analog voltage inputs  
n Logic inputs and outputs meet both MOS and TTL  
voltage level specifications  
n Works with 2.5V (LM336) voltage reference  
n On-chip clock generator  
n 0V to 5V analog input voltage range with single 5V  
supply  
General Description  
The ADC0801, ADC0802, ADC0803, ADC0804 and  
ADC0805 are CMOS 8-bit successive approximation A/D  
converters that use  
a
differential potentiometric  
ladder — similar to the 256R products. These converters are  
designed to allow operation with the NSC800 and INS8080A  
derivative control bus with TRI-STATE® output latches di-  
rectly driving the data bus. These A/Ds appear like memory  
locations or I/O ports to the microprocessor and no interfac-  
ing logic is needed.  
n No zero adjust required  
n 0.3" standard width 20-pin DIP package  
n 20-pin molded chip carrier or small outline package  
n Operates ratiometrically or with 5 VDC, 2.5 VDC, or  
analog span adjusted voltage reference  
Differential analog voltage inputs allow increasing the  
common-mode rejection and offsetting the analog zero input  
voltage value. In addition, the voltage reference input can be  
adjusted to allow encoding any smaller analog voltage span  
to the full 8 bits of resolution.
