HA12219NT
Audio Signal Processor for Cassette Deck
ADE-207-258A 2nd Edition July 1998 Description
HA12219NT is silicon monolithic bipolar IC providing PB equalizer, REC equalizer system and each electronic control switch in one chip.
Functions
· PB equalizer × 2 channel · REC equalizer × 2 channel · Each electronic control switch to change REC/PB etc. · REC MUTE · REC head return switch
Features
· REC equalizer is very small number of external parts, built-in 2 types of frequency characteristics. · PB equalizer circuit built-in. · REC /PB are possible with TYPE I/II. · Controllable from direct micro-computer output. · Available to reduce substrate-area because of high integration and small external parts.
