Description

HA12207NT is silicon monolithic bipolar IC providing PB equalizer, REC equalizer system and each electronic control switch in one chip.

Features

• REC equalizer is very small number of external parts, built-in 2 types of frequency characteristics.

• PB equalizer circuit built-in.

• REC /PB of high speed mode are possible with TYPE 1(Normal tape).

• Controllable from direct micro-computer output.

• Available to reduce substrate-area because of high integration and small external parts.

• As the pins arrangement resembles HA12185NT, it can design the board that is replaced with HA12185NT.

Functions

• PB equalizer × 2 channel

• REC equalizer × 2 channel

• Each electronic control switch to change REC/PB etc.
