CTL recording / playback amplifier
for VHS VCRs
BA8400FV
The BA8400FV is a CTL recording / playback amplifier developed for VHS VCRs. The playback amplifier has an
AGC circuit that can handle large input signal fluctuations, and a recording / playback switching circuit is provided to
allow high-speed switching.
•Applications
VHS-format VCRs
•Features
1) Can be operated off low power supply voltage (2.7V
to 3.5V).
2) Playback amplifier with AGC.
3) Fast switching between recording and playback.
