Block Diagram and Pin Configuration
Description
control IC for use in car radios/stereos and radio-
cassette recorders featuring serial data control. It
has improved over the CXA1846M/N by reducing
the ‘pop’ noise during volume level-switchings.
Features
• Volume adjustment (0dB to –87dB, – dB)
• Balance
• Serial data control (DATA, CLK, CE)
• Single 8V power supply
• Zero-cross detection circuit
Structure
The CXA1846AM/AN is an electrical volume
Bipolar silicon monolithic IC
Electronic volume control
