BD3461FS-E2

Audio Special Purpose Overview

The BD3461FS-E2 is a general-purpose 6-channel electronic volume controller manufactured by ROHM Semiconductor. It features an I2C bus interface for digital control and includes built-in advanced switches to minimize switching noise during volume changes. The device operates on a single power supply ranging from 7 V to 9.5 V with a typical operating current of 25 mA. Key performance metrics include a THD+N of 0.0004% (typical) and a channel separation of -109 dB (typical). It is housed in a 24-pin SSOP-A package and functions within a temperature range of -40°C to +85°C.
