General Description

HA12167FB/HA12169FB is silicon monolithic bipolar IC providing REC volume system, Level meter system and Dolby noise reduction system in one chip.

Functions • REC equalizer • Equalizer volume • Dolby B/C NR • REC/PB input electronic volume • Level Meter • DAC for adjusting bias × 2 channel × 2 channel × 2 channel × 2 channel × 2 channel × 2 channel

Key Features

Available to create characteristics of REC equalizer by changing external resistor, no coil.
Equalizer volume is available to calibrate recording automatically with micro-controller.
Electronic volume built-in is available to set the level of recording and play back automatically with micro-controller.
4 types of input (3 out of 4 are by way of electronic volume).
Input electronic control switching is irrelevant to REC/PB electronic control switching.
