Description
HA12207NT is silicon monolithic bipolar IC providing PB equalizer, REC equalizer system and each electronic control switch in one chip.
PB equalizer
REC equalizer
REC MUTE
REC head return switch × 2 channel × 2 channel
Each electronic control switch to change REC/PB etc.
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.
