General Description

HA12211NT is silicon monolithic bipolar IC providing REC equalizer system, PB equalizer system and each electronic control switch in one chip.

Functions • PB equalizer × 2 channel • REC equalizer × 2 channel • Each electronical control switch to change equalizer characteristics • REC mute • REC head return switch

Key Features

REC equalizer is very small number of external parts. (4 types of frequency characteristics built-in).
PB equalizer built-in. (A/B input changing system, 4 types of frequency characteristics).
Independent PB sensitivity for A deck, B deck.
Normal-speed/high-speed, normal tape/chrome tape switching built-in.
Controllable from direct micro-computer output.
Available to reduce substrate-area because of high integration and small external part.
