ADC08231/ADC08234/ADC08238 8-Bit 2 ms Serial I/O  
A/D Converters with MUX, Reference, and Track/Hold  
General Description  
Features  
Y
Serial digital data link requires few I/O pins  
The ADC08231/ADC08234/ADC08238 are 8-bit succes-  
sive approximation A/D converters with serial I/O and con-  
figurable input multiplexers with up to 8 channels. The serial  
I/O is configured to comply with the NSC MICROWIRETM  
serial data exchange standard for easy interface to the  
COPSTM family of controllers, and can easily interface with  
standard shift registers or microprocessors.

No zero or full scale adjustment required  
TTL/CMOS input/output compatible  
0V to 5V analog input range with single 5V power  
supply  
Designed for high-speed/low-power applications, the devic-  
es are capable of a fast 2 ms conversion when used with a  
4 MHz clock.  
All three devices provide a 2.5V band-gap derived reference  
with guaranteed performance over temperature.  
Y
Pin compatible with Industry-Standards ADC0831/4/8  
A track/hold function allows the analog voltage at the posi-  
tive input to vary during the actual A/D conversion.  
Key Specifications

2 ms (Max)  
The analog inputs can be configured to operate in various  
combinations of single-ended, differential, or pseudo-differ-  
ential modes. In addition, input voltage spans as small as 1V  
can be accommodated.
