BA7746S - VCR Hi-Fi audio signal REC / PB amplifier

Download the BA7746S datasheet PDF. This datasheet also covers the BA7 variant, as both devices belong to the same vcr hi-fi audio signal rec / pb amplifier family and are provided as variant models within a single manufacturer datasheet.

Description

Pin No.

Power supply for REC + B.

Connect to VCC (pin 7).

2 〈REC TC〉

REC + B time constant.

Use to adjust the REC + B rise time using the C value.

Features

  • REC MUTE and OVER REC functions. The playback system has a high-gain preamplifier, a low- offset head switch, VCA, and an EP-gain amplifier. In addition, all functions operate off a single 5V supply, and a H / L control system eliminates the need for special power supplies for the recording and playback systems. The IC has low power consumpution, and comes in a compact 32-pin SSOP-A package that requires little area on the PCB. It will improve the reliability and performance of your designs whil.

Video ICs VCR Hi-Fi audio signal REC / PB amplifier BA7746S / BA7746FS The BA7746S and BA7746FS contains the recording and playback amplifiers required for Hi-Fi VCR signal processing. The recording system uses a constant-current amplifier 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, VCA, and an EP-gain amplifier. In addition, all functions operate off a single 5V supply, and a H / L control system eliminates the need for special power supplies for the recording and playback systems.
