DDC112U/1K
双路电流输入20位模拟数字转换器 Dual Current Input 20-Bit ANALOG-TO-DIGITAL CONVERTER
DESCRIPON
The DDC112 is a dual input, wide dynamic range, charge digitizing analog-to-digital A/D converter 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.
