What are the key features of DDC114IRTCTG3?
- 20-bit delta-sigma ADC with 0.025% linearity error enables precise charge digitization for photodiode and low-current sensor arrays
- 4 simultaneous analog input channels with integrating front-end directly convert charge from sensors without external I-to-V amplifiers
- QFN-48 package with 5 V analog input range supports compact multichannel measurement systems in scientific instrumentation
What is DDC114IRTCTG3 used for?
DDC114IRTCTG3 is used in scientific instruments such as fluorescence spectrometers, CT scanners, and mass spectrometers where 4-channel simultaneous charge integration and 20-bit resolution are required for accurate low-light or low-current measurements. It serves industrial X-ray detector arrays and high-precision optical measurement systems where the integrating ADC front-end eliminates the need for discrete transimpedance amplifiers. Medical imaging equipment and analytical chemistry instruments benefit from its 0.025% linearity and wide 5 V input range.

Frequently Asked Questions
What ADC resolution and linearity does DDC114IRTCTG3 provide for precision charge measurement?
DDC114IRTCTG3 delivers 20-bit resolution with a maximum linearity error of 0.025% across its 4 analog input channels, making it suitable for precision charge digitization in fluorescence detectors and medical imaging arrays where even sub-picoamp signal accuracy is required.
How does the DDC114IRTCTG3's integrating front-end simplify photodiode array interface design?
The integrating ADC front-end in DDC114IRTCTG3 directly converts accumulated charge from up to 4 photodiodes into a 20-bit digital word without requiring external transimpedance amplifiers, reducing the signal chain to fewer than 5 passive components per channel and shrinking PCB area by over 40% compared to discrete I-to-V conversion approaches.
In which scientific instruments is DDC114IRTCTG3 preferred over a standard sigma-delta ADC for multichannel low-current sensing?
DDC114IRTCTG3 is preferred in fluorescence spectrometers, X-ray computed tomography detectors, and mass spectrometers because its 4-channel simultaneous charge integration captures parallel sensor data at 20-bit resolution with 0.025% linearity, whereas a standard sigma-delta ADC would require multiplexing and an external integrator stage, adding latency and noise to each of the 4 inputs.
