MONOLITHIC ANALOGUE INTEGRATED CIRCUIT

摘要

PURPOSE: To provide an analog integrated circuit that has all required analog support functions used together with an audio signal processing integrated circuit. CONSTITUTION: A monolithic analog integrated circuit is used together with an external audio integrated circuit to provide various analog support functions for the external audio integrated circuit. The single monolithic integrated circuit 50 includes a microphone amplifier, a speaker/headphone driver and a power control circuit 25 and also a power supply and a ground pin to operate the integrated circuit.
