Frequently Asked Questions
What makes DDC112 unique compared to regular ADCs?
The DDC112 directly digitizes current from photodiodes without external transimpedance amplifiers. Its charge-digitizing architecture integrates input current over a programmable time, then converts the accumulated charge to a 20-bit digital code, achieving exceptional dynamic range.
What is the dynamic range of DDC112?
The DDC112 achieves a remarkable 1:1,000,000 dynamic range, handling input charges from 350fC to 350pC. This 120dB range allows simultaneous measurement of strong and weak signals in CT scanner arrays without range switching.
How does the dual-channel architecture work?
The DDC112 contains two identical analog channels that operate in ping-pong mode: while one channel integrates the input current, the other is being digitized and read out. This continuous integrate-while-read architecture ensures zero dead time between measurements.
What applications is DDC112 designed for?
DDC112 is specifically designed for medical CT scanner detector readout, where arrays of photodiodes detect X-ray scintillation signals. It's also used in industrial X-ray inspection, scientific spectroscopy, and any application requiring high-precision current measurement.
