Dual Current Input 20-Bit  
ANALOG-TO-DIGITAL CONVERTER  
FEATURES  
DESCRIPTION  
● MONOLITHIC CHARGE MEASUREMENT ADC  
The DDC112 is a dual input, wide dynamic range,  
charge-digitizing analog-to-digital converter (ADC) with  
20-bit resolution. Low level current output devices,  
such as photosensors, can be directly connected to its  
inputs. Charge integration is continuous as each input  
uses two integrators; while one is being digitized, the  
other is integrating.  
● DIGITAL FILTER NOISE REDUCTION:  
3.2ppm, rms  
● INTEGRAL LINEARITY:  
±0.005% Reading ±0.5ppm FSR  
● HIGH PRECISION, TRUE INTEGRATING  
For each of its two inputs, the DDC112 combines  
current-to-voltage conversion, continuous integration,  
programmable full-scale range, A/D conversion, and  
digital filtering to achieve a precision, wide dynamic  
range digital result. In addition to the internal program-  
mable full-scale ranges, external integrating capacitors  
allow an additional user-settable full-scale range of up  
to 1000pC.  
FUNCTION  
● PROGRAMMABLE FULL SCALE  
● SINGLE SUPPLY  
● CASCADABLE OUTPUT  
APPLICATIONS  
● DIRECT PHOTOSENSOR DIGITIZATION  
To provide single-supply operation, the internal ADC  
utilizes a differential input, with the positive input tied  
to VREF. When the integration capacitor is reset at the  
beginning of each integration cycle, the capacitor  
charges to VREF. This charge is removed in proportion  
to the input current. At the end of the integration cycle,  
● CT SCANNER DAS  
● INFRARED PYROMETER  
● PRECISION PROCESS CONTROL  
● LIQUID/GAS CHROMATOGRAPHY  
● BLOOD ANALYSIS  
the remaining voltage is compared to VREF  
.
The high-speed serial shift register which holds the  
result of the last conversion can be configured to allow  
multiple DDC112 units to be cascaded, minimizing  
interconnections. The DDC112 is available in a SO-28  
package and is offered in two performance grades.
