AN3664NFB

Single chip audio signal processing IC for HiFi VCR

■ Overview

The AN3664FNB is a single chip IC which performs
HiFi VCR stereo audio signal processing. It incorporates
the PROM to maintain an adjusting value, enabling a com­plete adjustment-free use.

■ Features

• High precision and adjustment-free fO , recording/play-

back level and playback BPF by adoption of built-in
Zener zap PROM

• Enhanced cost performance due to incorporating exter-

nal parts.

■ Applications

• HiFi VCR
