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.
