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.
