CMOS IC Electronic Volume and Tone Control for Car Stereos

SANYO -> Panasonic 

Sample Application Circuit

LC75374E

Usage Notes

• The internal analog switches are in undefined states when power is first applied. Applications must therefore use

external circuits to mute the output until control data has been transferred.

• When setting up the initial data after power is first applied, applications must first transfer a set of IC initialization data.

This initialization data consists of an address field of (10000001) and a data field of all zeros (D0 to D43 = 0).

Applications must only send the actual initial data after this initialization data has been sent.

• Applications must either cover the CL, DI, and CE lines with the ground pattern or use shielded cables for these lines to

prevent the high-frequency digital signals that are transmitted over these lines from entering the analog signal system.
