Vcr Hi-fi Audio Signal Rec / Pb Amplifier With Flying-erase Oscillator - Rohm

The BA7745FS has the recording and playback Amplifiers required for Hi-Fi VCR signal processing, and also con- tains a flying-erase Oscillator The recording system uses a constant-current amplifeir with AGC to eliminate the need to adjust the recording current, and ensure stable operation as the head wears. The IC also features REC MUTE and OVER REC functions . The playback system has a high-gain preamplifier, a low-offset head Switch a VCA and an EP-gain Amplifier The flying-erase Oscillator has low 2nd and 3rd harmonic distortion, and when connected to an external driver large out- put current CAN be obtained. A H / L control system eliminates the need for special power supplies for the recording and playback systems. The IC has low power consumption, and comes in a compact 32-pin SSOP-P package that requires little area on the PCB. It will improve the reliability and performance of your designs while reducing external component requirements. By ROHM Co. Ltd.
