CDP68HC68A2, CMOS Serial 10-Bit A/D Converter

® Data Sheet CDP68HC68A2 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 convers
