CDP68HC68A2 Datasheet | Intersil

® Data Sheet April 2002 FN1963.4 CMOS Serial 10-Bit A/D Converter The CDP68HC68A2 is a CMOS 8-bit or 10-bit successive approximation analog to digital converter (A/D) with a standard Serial Peripheral Interface (SPI) bus and eight multiplexed analog inputs. Voltage referencing is user selectable to be relative to either VDD or analog channel 0 (AI0). The analog inputs can range between VSS and VDD. The CDP68HC68A2 employs a switched capacitor, successive approximation A/D conversion technique which provides an inherent sample-and-hold function. An onchip Schmitt oscillator provides the internal timing for the A/D converter. The Schmitt input can be externally clocked or...
