BA8400 Description
Video ICs 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.
