10-Bit Plus Sign Serial I/O A/D Converters with Mux,  
Sample/Hold and Reference  
General Description  
Features  
n 0V to analog supply input range  
n Serial I/O (MICROWIRE compatible)  
n Software or hardware power down  
n Analog input sample/hold function  
n Ratiometric or absolute voltage referencing  
n No zero or full scale adjustment required  
n No missing codes over temperature  
n TTL/CMOS input/output compatible  
The ADC12731, ADC12732 and ADC12734 are obsolete  
or on lifetime buy and included for reference only.  
This series of CMOS 10-bit plus sign successive approxima-  
tion A/D converters features versatile analog input multiplex-  
ers, sample/hold and a 2.5V band-gap reference. The 1-, 2-,  
4-, or 8-channel multiplexers can be software configured for  
single-ended or differential mode of operation.  
An input sample/hold is implemented by a capacitive refer-  
ence ladder and sampled-data comparator. This allows the  
analog input to vary during the A/D conversion cycle.  
Key Specifications  
In the differential mode, valid outputs are obtained even  
when the negative inputs are greater than the positive be-  
cause of the 10-bit plus sign output data format.  
n Resolution  
10 bits plus sign  
5V  
n Single supply  
n Power consumption  
n In power down mode  
n Conversion time  
n Sampling rate  
37 mW (Max)  
18 µW  
5µs (Max)  
74 kHz (Max)  
2.5V 2% (Max)  
The serial I/O is configured to comply with the NSC MI-  
CROWIRE serial data exchange standard for easy inter-  
face to the COPS and HPC families of controllers, and  
can easily interface with standard shift registers and micro-  
processors.  
n Band-gap reference  
Applications  
n Medical instruments  
n Portable and remote instrumentation  
n Test equipment
