Panasonic AN3370K Datasheet
ICs for VCR
■ Overview
The AN3370K can amplify high-frequency current generated by the built-in oscillator and drive the Flying-erase
head. This IC also allows to set an oscillation frequency
and an output current optionally with external constants
according to the erase head.
■ Features
•
Built-in high-accuracy, stable oscillator.
•
Capable of varying output current value and an oscillation frequency with external constants.
