BD3850FS-E2 Audio Sound Processor | ROHM Semiconductor
N.º de pieza: BD3850FS-E2 ✓ ActivoBD3850FS-E2 Descripción general
An audio sound processor is a specialized integrated circuit that receives, organizes, and controls audio signals within a larger audio system. In the product hierarchy, it belongs to the broader class of audio amplifiers and then to integrated circuits and semiconductors. Such devices can simplify board partitioning by consolidating channel routing, gain control, or other signal-conditioning functions into one package.
The BD3850FS-E2 is identified by its distributors as an Audio Special Purpose or Audio Channel device. The associated documentation describes the device family as a sound processor and shows a 24-pin SSOP-A24 package. This surface-mount package supports compact equipment designs while providing enough external connections for a multi-channel audio architecture.
Because this part is specifically intended for audio-channel processing, it is relevant to equipment that routes or conditions multiple sound paths. A sound processor can reduce the number of separate routing and gain-control blocks required around amplifiers, converters, and output stages. Exact channel count, voltage ratings, gain settings, and interface timing should be confirmed from the ROHM Semiconductor datasheet before schematic capture.
Typical application directions include surround-sound systems, powered speakers, compact home-audio equipment, and industrial audio panels. Its 24-pin SSOP-A24 package makes it more appropriate for established through-hole-era board layouts than for exceptionally dense portable layouts. Pin assignment, exposed thermal behavior, and decoupling requirements remain central to successful implementation.
During PCB design, route analog audio inputs and outputs away from switching nodes and high-current return paths. Confirm that the PCB land pattern matches SSOP-A24 rather than a visually similar 24-pin package. Use the manufacturer reference circuit for recommended input and output networks, power-supply connection, and component values.
This product page consolidates the exact ordering code, package information, sourcing structure, and engineering guidance needed to evaluate the BD3850FS-E2. The comparison and design notes also help distinguish package compatibility, circuit integration, and application fit before committing a new audio design to this sound processor.

Aplicaciones típicas
BD3850FS-E2 es adecuado para 6 aplicacións: Multi-Channel Home Audio, Powered Speaker Signal Control, Surround-Sound Processing, Industrial Audio Control Panel, Compact AV Receiver Electronics, Audio Interface and Mixer Card.
Multi-Channel Home Audio
The BD3850FS-E2 can serve as the central sound-processing element in a home-audio board that manages several signal paths. Its documented 24-pin SSOP-A24 package provides a practical way to consolidate channel-related functions while retaining a conventional surface-mount footprint. The designer should map the required source, output, control, and grounding connections against the manufacturer pin table before placement. This approach is especially useful when replacing a board organized around a dedicated multi-channel sound processor.
Powered Speaker Signal Control
In a powered-speaker controller, the BD3850FS-E2 can support centralized audio-channel processing ahead of output amplification. Integrating the sound-processing stage can simplify routing among inputs, tone sections, and speaker channels. The 24-pin package provides numerous external connections, allowing each functional path to be reviewed clearly on the schematic. Signal-level compatibility, control polarity, and decoupling must be verified from the exact datasheet before the amplifier and speaker network are finalized.
Surround-Sound Processing
BD3850FS-E2 is relevant to surround-sound equipment where several audio paths require consistent organization and control. A dedicated sound processor can reduce the amount of board area devoted to separate channel-routing networks while preserving a clear IC-based design structure. Its SSOP-A24 package is suitable for a conventional audio PCB, although the land pattern must be checked for exact dimensions. Use the reference circuit to establish channel assignment, grounding, and passive-component values.
Industrial Audio Control Panel
An industrial audio control panel can use the BD3850FS-E2 when it requires coordinated handling of several audio channels within a limited board area. The integrated sound-processing function may reduce discrete routing complexity and simplify PCB partitioning compared with a network of separate channel ICs. Because industrial environments may impose stricter temperature and immunity expectations, engineers should review the exact operating limits, protection strategy, and grounding implementation. Digital control or isolation requirements must also be confirmed before final architecture selection.
Compact AV Receiver Electronics
The BD3850FS-E2 can be evaluated for compact AV receiver electronics that coordinate multiple internal audio paths. Its 24-pin SSOP-A24 package provides enough external connectivity for a structured channel implementation while remaining compatible with conventional multilayer PCB assembly. Designers should use the pin table to define the signal-flow topology and isolate noisy power stages from audio routing. Exact channel behavior and signal-conditioning requirements determine whether the device matches the selected receiver architecture.
Audio Interface and Mixer Card
For a dedicated audio interface or mixer card, BD3850FS-E2 offers a centralized sound-processing block when the required functions align with its channel implementation. The surface-mount SSOP-A24 package supports automated assembly and orderly connector routing on a multi-layer board. External resistors and capacitors may be necessary to establish gain and source selection, but their values should follow the manufacturer reference circuit. Confirm input sensitivity and output-loading requirements before selecting the surrounding analog components.

Diferenciadores clave

Notas de diseño
Use the manufacturer land pattern for SSOP-A24 and verify pin 1 orientation against the PCB silkscreen and device marking. A 24-pin package can differ in lead pitch, body width, and span, so a visual footprint match is not sufficient. Preserve the manufacturer's recommended copper pattern and component clearances, and confirm every external connection against the pin-description table before releasing the layout.
Route audio traces away from switching nodes, high-current driver outputs, inductors, and fast digital edges. Keep the ground path beneath and around the IC continuous, and return analog and digital currents separately to the appropriate star point. Follow the reference circuit for input and output networks because unverified resistor or capacitor substitutions can alter gain, bandwidth, channel balance, and noise performance.
Do not substitute a BD3850-family part solely because it also has 24 pins. The -E2 suffix, package drawing, pin functions, channel arrangement, supply requirements, and absolute maximum ratings must all be checked. When replacing an existing design, create a pin-by-pin compatibility table and document any function that changes; otherwise, a matching pin count can conceal an incompatible replacement.
Design the supply path around the exact datasheet requirements for operating voltage, current, bypass capacitance, and startup behavior. Place each required decoupling capacitor close to its assigned power pin and minimize loop area between the capacitor and IC. Check the supply rail for ripple and disturbance generated by neighboring amplification or switching stages, because an audio sound processor may amplify noise present on its input or supply references.
Información de cumplimiento
The available product records do not state RoHS, REACH, halogen-free, lead-free, or conflict-minerals status. AEC-Q100 qualification is treated as not applicable because the part is identified for general audio processing rather than an automotive-qualified ordering option.
