BD88410GUL-E2

Audio Amplifiers Overview

The BD88410GUL-E2 is a Class-B, two-channel stereo headphone amplifier manufactured by ROHM Semiconductor. It operates on a single power supply ranging from 2.4V to 5.5V and utilizes a coupling capacitorless (C-less) output architecture. The device delivers up to 80mW per channel into a 16Ω load or 60mW per channel into a 32Ω load. Key electrical specifications include a total harmonic distortion plus noise (THD+N) of 0.006% at 16Ω, a signal-to-noise ratio of 101dB, and a standby current of 0.1µA. It features an 80µs start-up time and operates within a temperature range of -40°C to +85°C.
