Overview
The BD3812F-E2 is a two-channel audio signal processor manufactured by Rohm Semiconductor, designed for consumer audio applications. It operates within a supply voltage range of 5V to 7.3V and features a serial interface for control. The device is housed in a 14-SOP (SOIC) package with a width of 4.40mm, suitable for surface mount installation. It functions as an electronic volume controller with gain amplifier capabilities, supporting independent channel control. The component is rated for operation between -20°C and +75°C.
Feature Summary
- Two-channel independent volume control with 1dB step resolution
- Serial interface compatible with 3.3V and 5V logic levels
- Low residual noise performance with high dynamic range
- Supports cascading up to four chips on a common bus line
Applications
- AV receivers
- Home theater systems
- Mini-component systems
Procurement Notes
Verify the current lifecycle status before procurement, as the BD3812F-E2 has been identified as an End-of-Life product in public records. Confirm availability through authorized distributors or secondary markets if active sourcing is required. Ensure the 14-SOP package dimensions match the target PCB footprint design constraints.
Selection Notes
Select this component for designs requiring precise digital volume control in stereo audio paths. The 5V to 7.3V supply range suits single-supply consumer electronics. Consider the serial interface requirements for microcontroller connectivity. Verify that the thermal operating range of -20°C to +75°C meets the environmental specifications of the final application enclosure.
Part Context
The BD3812F-E2 belongs to the BD3812F series of sound processors from Rohm Semiconductor. It serves as a specialized integrated circuit for managing audio signals in home entertainment equipment. The 'E2' suffix typically denotes specific manufacturing or compliance variations within the series, though functional parameters remain consistent with the base BD3812F model.
Replacement Considerations
Public documentation indicates the BD3812F-E2 is discontinued. No direct public substitute part numbers are confirmed in the provided source material. Engineers should evaluate alternative Rohm audio processors or generic volume control ICs based on pin compatibility and electrical specifications.
