ADC08831/ADC08832  
8-Bit Serial I/O CMOS A/D Converters with Multiplexer  
and Sample/Hold Function  
n Remote sensing in noisy environments  
n Instrumentation  
The ADC08831/ADC08832 are 8-bit successive approxima-  
n Embedded Systems  
General Description  
tion Analog to Digital converters with 3-wire serial interfaces  
and a configurable input multiplexer for 2 channels. The se-  
Features  
rial I/O will interface to COPS family of micro-controllers,  
PLD’s, microprocessors, DSP’s, or shift registers. The serial  
n 3-wire serial digital data link requires few I/O pins  
n Analog input track/hold function  
I/O is configured to comply with the NSC MICROWIRE se-  
rial data exchange standard.  
n 2-channel input multiplexer option with address logic  
n Analog input voltage range from GND to VCC  
n No zero or full scale adjustment required  
n TTL/CMOS input/output compatible  
To  
minimize  
total  
power  
consumption,  
the  
ADC08831/ADC08832 automatically go into low power  
mode whenever they are not performing conversions.  
A track/hold function allows the analog voltage at the positive  
input to vary during the actual A/D conversion.  
n Superior pin compatible replacement for ADC0831/2  
The analog inputs can be configured to operate in various  
Key Specifications  
combinations  
of  
single-ended,  
differential,  
or  
n Resolution: 8 bits  
pseudo-differential modes. The voltage reference input can  
be adjusted to allow encoding of small analog voltage spans  
to the full 8-bits of resolution.  
=
n Conversion time (fC 2 MHz): 4µs (max)  
n Power dissipation: 8.5mW (typ)  
n Low power mode: 3.0mW (typ)  
n Single supply: 5VDC  
Applications  
n Digitizing sensors and waveforms  
n Process control monitoring  
±
n Total unadjusted error:  
1LSB  
n No missing codes over temperature
