BH7272KV 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 damping circuit.
4) Recording limit amplifier is included. Recording AGC amplifier not included.
5) The signal system VCC is 4.9V, and the control system VCC is 3.0V.
