HA12206 - Hitachi Semiconductor

HA12206 Audio Signal Processor

HA12206NT is silicon monolithic bipolar IC providing music sensor system, ALC, REC equalizer system and each electronic control switch in one chip. Functions • REC equalizer • Line Amp. × 2 channel × 2 channel • ALC (Automatic Level Control) • MS (Music Sensor) • Each electronic control switch to change REC equalizer, bias, etc. • REC mute Features • REC .

Features

• REC equalizer is very small number of external parts, built-in 2 types of frequency characteristics.
• Correspondence with normal position (TYPE I) / high position (TYPE II).
• TYPE I / TYPE II and PB equalizer fully electronic control switching built-in.
• Controllable from direct micro-computer output.
• Available to reduce substrate-area because of high integration and small external parts. HA12206NT Pin Description, Equivalent Circuit (VCC = 7.0V, VEE =
