BD37513FS-E2

Audio Special Purpose Overview

The BD37513FS-E2 is a sound processor IC by Rohm Semiconductor designed for audio tone control applications. It features a built-in two-band equalizer (bass and treble) with adjustable parameters, eliminating the need for external filter components. The device supports four independent output channels and includes an input selector. It operates on a single power supply ranging from 7V to 9.5V, with an operating temperature range of -40°C to +85°C. The component utilizes an I2C bus interface for digital control and is housed in a 20-SSOP-A package.

Audio Special Purpose Feature Summary

• Built-in 2-band equalizer (bass/treble) requiring no external filter parts
• Four-channel independent volume control with input selection
• I2C bus interface for digital control
• Single supply voltage operation: 7V to 9.5V

Audio Special Purpose Applications

• Audio tone processing systems
• Standard home audio equipment
• Sound processors requiring integrated EQ

Audio Special Purpose Procurement Notes

Verify the specific suffix 'E2' against the manufacturer's current datasheet to confirm packaging details and RoHS compliance status. Ensure the 20-SSOP-A package dimensions match the target PCB footprint. Confirm that the I2C address configuration meets system requirements before finalizing procurement.

Audio Special Purpose Selection Notes

Select this component when a compact solution for bass and treble adjustment is required without external passive components. It is suitable for designs needing four-channel output control via a digital interface. Verify that the 7V–9.5V supply range aligns with the system power architecture and that the -40°C to +85°C temperature range covers the operational environment.

Audio Special Purpose Part Context

This part belongs to Rohm's series of sound processors aimed at standardizing control software and circuit boards across product lines. It integrates tone control functions to reduce external component count and simplify design. The BD37513FS-E2 is distinct from other models in the family by its specific channel count and equalizer band configuration.
