BH7272KV - Two-channel VCR PRE / REC amplifier for Digital VCRs

Datasheet Summary

Features

  • 1) The playback amplifier is a differential amplifier with an overall gain of 54dB (Typ. ), and has low-noise transistors as the first stage. The feedback circuit is not included, so provide negative feedback for head peak damping, and positive feedback to cancel the input capacitance using external components. 2) The playback AGC amplifier has ± 10dB of control range. 3) The recording current amplifier is a BLT current amplifier. Use external components to construct the head peak damp.

Video ICs Two-channel VCR PRE / REC amplifier for Digital VCRs BH7272KV The BH7272KV is a head amplifier developed for use in digital video cassette recorders. Both PB and REC have excellent frequency characteristics making this IC an ideal choice for digital recording and playback. The small VQFP48 package facilitates compact design of portable equipment such as video cameras. Applications • Digital video cassette recorders Features • 1) The playback amplifier is a differential amplifier with an overall gain of 54dB (Typ.), and has low-noise transistors as the first stage. The feedback circuit is not included, so provide negative feedback for head peak damping, and positive feedback to cancel the input capacitance using external components.
