Features:

CD3313 is an audio processing circuit with volume, tone (bass, treble), balance (left, right) and loudness (front, back) control, PIN√PINPT2313; TDA7313


The circuit provides input gain selection and local loudness control functions. All controls are operated through a serial I²C bus that can be connected to a microcomputer; various AC amplitude-frequency characteristics can be set by combining an external resistor-capacitor network with an internal operational amplifier.


Due to the use of high-performance bipolar/CMOS process technology, low distortion, low noise and low DC level drift are achieved.
