HA12207NT Datasheet Audio Signal Processor

Manufacturer: Hitachi Semiconductor (now Renesas)

Overview: HA12207NT Audio Signal Processor for Cassette Deck ADE-207-197B (Z) 3rd Edition Jun.

General Description

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

Functions • PB equalizer • REC equalizer • REC MUTE • REC head return switch × 2 channel × 2 channel • Each electronic control switch to change REC/PB etc.

Key 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. HA.
