DDC112U/1K Datasheet PDF - TI

DESCRIPTION

●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.
