Référence : BD3823FV-E2 ✗ Fin de vieBD3823FV-E2 Présentation
An audio signal processor is an interface IC that conditions, selects, and controls multiple audio paths within an entertainment system. Its place in the product hierarchy is audio signal processor, interface IC, audio subsystem, and electronic control component. The BD3823FV-E2 is intended specifically for DVD recorders and related consumer-video equipment where several standard audio channels must be routed while keeping the reproduced signal quiet and acoustically transparent.
The primary features include five-channel selection, low output noise of 3.2 uVrms, and low distortion of 0.0015%. Its 7 V to 14.5 V operating range accommodates the supply voltages commonly found in multi-rail consumer-electronics equipment, while its -40°C to +85°C operating-temperature range supports industrial temperature conditions. An I2C interface permits a host controller to configure the processor rather than relying exclusively on mechanical switches.
The 20-pin SSOP-B package uses surface-mount technology and provides a compact implementation for audio-processing functions. Because the package has closely spaced leads, assembly processes should be qualified for the specified lead pitch and soldering profile. The device integrates multiple signal-processing functions instead of requiring a separate selector and volume-control arrangement, reducing the number of discrete signal-path components in a DVD recorder.
Typical uses include DVD recorder audio routing, NTSC and PAL video-system audio interfaces, multichannel consumer-audio selection, and embedded audio-control subsystems. The processor can serve as the central interface between audio sources, amplifier or codec stages, and the recorder's system controller. Its low-noise and low-distortion characteristics are especially relevant where preserving the original recording signal is more important than simply switching channels.
Design the power rails so that the 7 V to 14.5 V operating range is maintained under load, and place the device's decoupling capacitors close to the supply and ground connections. Confirm the board footprint and pin orientation against the ROHM Semiconductor datasheet before layout release. PCB review should also check signal return paths, ground continuity, and keepouts around the SSOP-B leads.
This page combines the ROHM Semiconductor device description, package and operating characteristics, sourcing guidance, and practical design considerations into a focused engineering reference. It also distinguishes documented functions from parameters that require confirmation in the manufacturer datasheet, helping engineers evaluate the BD3823FV-E2 before committing a board design to this specialized audio interface.

Applications typiques
BD3823FV-E2 convient pour 6 applications: DVD Recorder Audio Routing, NTSC Consumer Audio Interface, PAL Consumer Audio Interface, Multichannel Audio Source Selection, Consumer-Video Audio Control, Analog Audio Level Management.
DVD Recorder Audio Routing
The BD3823FV-E2 fits a DVD recorder because it combines a five-channel selector with a resistor-ladder volume function in one dedicated audio interface. According to the ROHM Semiconductor datasheet, the device supports NTSC and PAL systems, helping the recorder select the required audio route and set the playback level without duplicating those functions across separate control blocks. Its 3.2 uVrms noise and 0.0015% distortion specifications support low-noise signal handling, while I2C control allows a system controller to configure operating states. The implementation should follow the manufacturer application circuit for pin assignment, bypassing, and signal-path layout.
Recommandé
NTSC Consumer Audio Interface
BD3823FV-E2 is suitable for an NTSC audio subsystem that requires centralized channel selection and volume control. The manufacturer datasheet identifies NTSC support as an intended application for the five-channel selector, allowing the device to serve as the interface between the recorder's audio paths and downstream amplification or codec circuitry. Its documented 3.2 uVrms noise and 0.0015% distortion are useful when preserving the source signal is a priority. With a 7 V to 14.5 V supply range, the IC fits compatible multi-rail consumer equipment, subject to correct decoupling and confirmed pin-level implementation.
Recommandé
PAL Consumer Audio Interface
The BD3823FV-E2 can support PAL-based consumer-audio equipment by combining five-channel selection with resistor-ladder volume control. This integration gives the system controller a single dedicated interface for routing and level management instead of distributing those functions among separate selectors. According to the ROHM Semiconductor documentation, the processor supports PAL systems and is targeted at DVD-recorder applications. Its 3.2 uVrms noise specification and 0.0015% distortion are appropriate for a clean audio path, while the -40°C to +85°C temperature range supports equipment intended for industrial operating conditions.
Recommandé
Multichannel Audio Source Selection
Use BD3823FV-E2 when a multichannel recording system needs a dedicated five-way audio selector with integrated level control. The resistor-ladder volume function provides a defined analog attenuation structure within the signal path, while the selector determines which source is presented for downstream processing. The 3.2 uVrms noise figure makes the device relevant to low-level audio routing, and the 0.0015% distortion specification supports transparent channel changes. Designers should follow the ROHM Semiconductor application schematic and pin descriptions to establish signal reference, grounding, and external component requirements around the 20-pin SSOP-B device.
Recommandé
Consumer-Video Audio Control
BD3823FV-E2 provides a focused signal-processing block for consumer-video equipment that must route and attenuate multiple audio channels under software control. The I2C interface supports configuration by a host controller, reducing the need for dedicated manual controls or discrete logic. The device's dedicated audio role and 20-pin SSOP-B package are consistent with compact DVD-recorder and related system architectures. Its low-noise and low-distortion characteristics help protect fidelity through the selection and volume stages. A robust implementation requires stable 7 V to 14.5 V supply operation, correct pin definitions, and careful return-path design around the surface-mount package.
Recommandé
Analog Audio Level Management
The BD3823FV-E2 can be used as the analog level-management element in a DVD-recorder signal chain because it incorporates both channel selection and a resistor-ladder volume function. This architecture helps maintain consistent signal handling between a selected source and the next amplification, conversion, or output stage. According to the manufacturer datasheet, the device operates from 7 V to 14.5 V and offers 3.2 uVrms noise with 0.0015% distortion. Its I2C control supports configurable operation from a system controller. PCB designers should reproduce the reference circuit, verify analog grounding, and place bypassing components close to the relevant supply pins.

Notes de conception
Use the ROHM Semiconductor package drawing to reproduce the 20-pin SSOP-B footprint, including lead pitch, lead width, solder-paste geometry, and pin-1 orientation. Place the device so short audio traces can reach the associated input and output networks. Keep the footprint free of unintended copper beneath the package unless the manufacturer drawing explicitly permits it, and verify the PCB library against the actual ordering code before fabrication.
Follow the manufacturer application circuit for analog signal routing and ground-return configuration. Place input and output bypass or signal-conditioning components close to their assigned pins to limit parasitic inductance and preserve the documented 3.2 uVrms noise and 0.0015% distortion behavior. Route I2C control traces away from sensitive audio paths where practical, and maintain a continuous return reference for every routed audio channel.
Design the supply network so BD3823FV-E2 receives a stable voltage within its documented 7 V to 14.5 V operating range under load and temperature. Place supply decoupling at the device pins with the shortest possible current-loop path, and keep high-current switching-node copper separated from the audio section. Use the manufacturer reference circuit to confirm the required capacitor type, placement, and any additional supply-network components.
Do not treat a device with the same SSOP body size as automatically pin compatible. The replacement must match all 20 pin assignments, I2C behavior, channel-selection logic, resistor-ladder volume function, supply range, and audio electrical characteristics. Verify lifecycle requirements as well, because the BD3823FV-E2 is listed as obsolete and a long-term sourcing plan should address traceability, date-code control, and qualification of any substitute.
