DDC112UK/1K Datasheet PDF - Burr Brown

DESCRIPTION

●The DDC112 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.
