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.

Y
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

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.
