Product Summary
The DDC112UK 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. The applications of the DDC112UK are (1)direct photosensor digitization; (2)ct scanner das; (3)infrared pyrometer; (4)precision process control; (5)liquid/gas chromatography; (6)blood analysis.
Parametrics
DDC112UK absolute maximum ratings: (1)AVDD to DVDD: –0.3V to +6V; (2)AVDD to AGND: –0.3V to +6V; (3)DVDD to DGND: –0.3V to +6V; (4)AGND to DGND: ±0.3V; (5)VREF Voltage to AGND: –0.3V to AVDD +0.3V; (6)Digital Input Voltage to DGND: –0.3V to DVDD +0.3V; (7)Digital Output Voltage to DGND: –0.3V to DVDD +0.3V; (8)Package Power Dissipation: (TJMAX – TA)/θJA; (9)Maximum Junction Temperature (TJMAX): +150℃; (10)Thermal Resistance, θJA: 150℃/W; (11)Lead Temperature (soldering, 10s): +300℃.
Features
DDC112UK features: (1)monolithic charge measurement adc; (2)digital filter noise reduction: 3.2ppm, rms; (3)integral linearity: ±0.005% reading ±0.5ppm fsr; (4)high precision, true integrating function; (5)programmable full scale; (6)single supply; (7)cascadable output.
