Description: The BH3857AFV is a signal-processing IC for controlling audio quality in CD radio-cassette players and mini-component
| Parameter | Symbol | Limits | Unit | |
| Applied voltages | VEE | 4.5 | V | |
| Power dissipation | Pd | 1000 | mW | |
| Operating temperature | Topr | 40 ~ + 85 | °C | |
| Storage temperature | Tstg | 55 ~ + 150 | °C | |
| Port pin voltage | PORT1~PORT4 | 15.0 | V | |

1) Volume (main volume) and tone (bass and treble) control possible by direct serial link to a microprocessor. DC control is also possible.
2) Volume control is done with a low-distortion, low- noise VCA, and step noise is suppressed.
3) The gain of the input amplifier can be adjusted, and two surround matrixes are available to expand the sound.
4) The IC includes a stable reference voltage source and input buffer to reduce external component requirements, and comes in a compact 40-pin SSOP package that is perfect for compact designs.
5) Four open-collector outputs are provided to make logic control possible.
