Abstract
Power shutdown of an integrated circuit such as a data acquisition system is implemented by software command. In one embodiment of a data acquisition system, an 8 bit data input word for configuring the operation of the data acquisition system includes two word length bits which define the length of data output words. One combination of the word length bits is utilized to command power shutdown. A decoder within the integrated circuit identifies the power shutdown command and generates a power shutdown signal (PS) to minimize power consumption when the circuit is not in operation.
