BD3452KS is a sound processor that integrates functions including Input Selector, 8ch Volume and Gain Amp for applications such as AV receivers, home theater systems and mini-component systems. Adopting the BiCMOS process achieves low distortion, low noise and a wide dynamic range.
The BD3452KS is an 8‑channel sound processor that integrates input selection, volume control, gain amplification and serial control in a single BiCMOS chip. It is intended for AV receivers, home‑theater systems and mini‑component devices.
The document lists electrical characteristics, maximum ratings, timing requirements, typical application circuits and thermal derating data, along with ordering information and usage notes for safe implementation.
| Dynamic range | 132 dB |
|---|---|
| Master volume range | 0 to -99 dB |
| Power supply voltage (VCC) | Typical 7 V |
| Operating temperature range | -20 °C to +75 °C |
| Power dissipation | 1300 mW |
When starting up, VEE and VCC should be powered on simultaneously or VEE first, then followed by VCC.
The maximum output voltage (Vomax) is 3.6 V rms (typical 4.2 V rms).
The input impedance is specified as 32 kΩ to 62 kΩ.
