BD3882FV-E2 - 2-Channel Sound Processor | ROHM
部品番号: BD3882FV-E2 ✓ 生産中BD3882FV-E2 概要
An audio sound processor is an application-specific integrated circuit that combines multiple functions required by analog audio equipment. Within the product hierarchy, it is an audio signal processor, an integrated circuit, and a semiconductor. Unlike a general-purpose DSP, this device is optimized for compact cassette and stereo systems, where recording and playback signal paths require coordinated level and mode control rather than programmable digital processing.
ROHM describes the BD3882FV family as a sound processor for radio cassette recorders and mini component stereos. The BD3882FV-E2 is categorized as an audio special-purpose IC and a 2-channel device. Its 40-SSOP-B package supports dense PCB layouts while providing the pin count needed for a multifunction analog audio subsystem. The -E2 ordering suffix identifies the specific supplied device variant.
The architecture is described as a silicon monolithic integrated circuit, and a related technical listing identifies the BD3882 as a BiCMOS audio circuit. This combination places the device between simple discrete audio control and more complex programmable processing. Its implementation is intended for ordinary audio-visual, office-automation, communications, electrical-appliance, and electronic-toy equipment, as stated in the ROHM datasheet.
Typical uses include cassette-recorder playback and recording control, mini stereo signal routing, home-audio channel processing, and compact multimedia equipment. In these systems, the sound processor can organize dual-channel audio functions while reducing the number of separate analog control components. The 40-pin package is particularly relevant where board area is constrained but multiple audio signal paths must remain accessible.
Designers should use the pin-description table, typical application circuit, and electrical characteristics in the manufacturer datasheet when assigning each signal. Input and output decoupling, grounding, signal levels, mode-control logic, and supply bypassing must follow the recommended circuit because the device is intended for a specific analog audio architecture rather than general-purpose signal routing.
This page consolidates the device identity, package, channel count, application role, ordering information, source links, and engineering guidance into a compact selection reference. It also distinguishes documented BD3882FV family information from the exact BD3882FV-E2 ordering variant and focuses replacement decisions on verified, pin-compatible options.

主な用途
BD3882FV-E2 の用途: 6 件s: Radio Cassette Recorder, Mini Component Stereo, Compact Home-Audio Head Unit, Dual-Channel Analog Audio Module, Portable Media Audio Deck, Audio-Visual Equipment Sound Path.
Radio Cassette Recorder
The BD3882FV-E2 fits a radio cassette recorder because ROHM identifies the BD3882FV family as a sound processor for that equipment type. Its 2-channel architecture supports the shared audio paths characteristic of compact cassette products, while the 40-SSOP-B package limits board footprint. Engineers should use the manufacturer’s typical application circuit to establish record, playback, and control connections. The external network remains important because signal levels, mode transitions, and bypass behavior depend on the complete reference design rather than only on the integrated functions.
おすすめ
Mini Component Stereo
The BD3882FV-E2 is directly aligned with mini component stereo systems, one of the applications named for the BD3882FV family. Its 2-channel audio processing role and 40-pin surface-mount package are suited to compact hi-fi products where multiple sound-control functions must be consolidated. The implementation should follow the ROHM pin-description table and typical circuit to preserve the intended dual-channel behavior. Power bypassing and signal grounding should be planned around the manufacturer layout recommendations to avoid introducing noise into the audio path.
おすすめ
Compact Home-Audio Head Unit
The BD3882FV-E2 can serve as the sound-processing element in a compact home-audio head unit that uses a cassette-style analog architecture. Its 2-channel structure matches left and right audio paths, while the 40-SSOP-B package allows the device to coexist with amplifiers, selectors, and level-control circuitry on a dense board. Because the IC is application-specific, it should not replace a generic audio switch without verifying every active level and control condition. The manufacturer’s mode diagram and application circuit provide the appropriate basis for a new design.
おすすめ
Dual-Channel Analog Audio Module
The BD3882FV-E2 is appropriate for a dedicated dual-channel analog audio module built around the manufacturer’s intended cassette and stereo control functions. Consolidating the sound-processing IC into one 40-pin package reduces the number of discrete stage connections while retaining two independent audio channels. Integration still requires careful treatment of the supply rail, input and output signal levels, and mode-control logic. Prototyping should reproduce the ROHM reference network closely before component values or routing are changed, particularly around switching and bypass transitions.
おすすめ
Portable Media Audio Deck
The BD3882FV-E2 can be evaluated for a portable media audio deck whose architecture resembles a cassette recorder or mini stereo. The device’s 2-channel format and 40-SSOP-B package make it practical for a compact board, while its dedicated sound-processing role can simplify control of the analog signal path. Portability adds strict board-area and power constraints, making component integration valuable. Engineers must still account for the stated 4.5 V to 9 V supply range and verify startup, mode control, and signal-level requirements against the manufacturer guidance.
おすすめ
Audio-Visual Equipment Sound Path
The BD3882FV-E2 is suitable for audio-visual and communications equipment that incorporates a compact analog stereo sound path. ROHM states that the BD3882FV family can be used with ordinary audio-visual equipment, office-automation equipment, communications devices, electrical appliances, and electronic toys. Its dedicated 2-channel processing reduces the need to reproduce several control functions with scattered discrete logic. Adoption should be based on matching the target product to the cassette or mini-stereo reference architecture, since the device is specialized rather than a universal audio routing component.

設計ノート
Start the layout from the ROHM typical application circuit and preserve the relative placement of the sound processor, external components, and signal connections. The 40-SSOP-B footprint has closely spaced leads, so inspect solder-mask clearance and fanout carefully. Keep analog input and output routing away from high-current switching paths. If the function is redesigned rather than copied, validate every mode-control state against the pin-description table and mode diagrams.
Design the supply network for the stated 4.5 V to 9 V operating range and place the required bypass capacitors at the device pins according to the manufacturer layout. Keep the supply trace short and provide a low-impedance return path to the device ground. If the sound processor shares a board with switching regulators or display circuitry, isolate noisy currents physically and decouple the audio section locally. Verify startup behavior and mode transitions in hardware because the application circuit may impose specific rail conditions.
Do not treat the base part number BD3882FV as proof that every ordering variant is interchangeable with BD3882FV-E2. Confirm the suffix, 40-SSOP-B package, pin assignments, and electrical limits before approving a substitution. Likewise, avoid assuming that a generic stereo switch or DSP is pin-compatible. The device implements a manufacturer-specific analog sound-processing architecture, and changes to signal levels, mode logic, or external component values can change playback and recording behavior.
コンプライアンス情報
The ROHM datasheet states that the BD3882FV family is intended for ordinary audio-visual, office-automation, communications, electrical-appliance, and electronic-toy equipment. It does not establish RoHS, REACH, lead-free, halogen-free, conflict-minerals, or automotive qualification status for the exact BD3882FV-E2 ordering code. AEC-Q100 is not applicable because the product is not presented as an automotive-qualified device.
