This manual introduces the application information of ROHM products, mainly including product introduction, application circuit diagram, application circuit parameters, etc., which can help users quickly understand the product features and usage.
The BD3826FS is a silicon monolithic integrated circuit designed for audio signal switching in DVD recorders and other electronic equipment. The document provides electrical characteristics, pin assignments, absolute maximum ratings, and application guidelines.
Key features include low total harmonic distortion (0.002 % typ.), high signal‑to‑noise ratio (90 dB typ.), and a built‑in mute function for multi‑input configurations. The datasheet also lists recommended power‑on sequencing and cautions for safe use.
| Supply voltage 1 (VEE1) | +4.5~+5.5 V |
|---|---|
| Supply voltage 2 (VEE2) | –6.5~–4.5 V |
| Supply voltage 3 (VEE3) | +11.5~12.5 V |
| Power dissipation | 950 µW |
| THD (typ.) | 0.002 % |
| Signal‑to‑noise ratio (typ.) | 90 dB |
| Crosstalk (typ.) | -100 dB |
| Output resistance (max) | 350 Ω |
| Operating temperature range | -25 °C ~ +75 °C |
The typical THD is 0.002 %.
VEE1 may be supplied up to +5.5 V.
The –5 V pin should not go below its nominal voltage; keep it near –5 V during operation.
