FAN3800 — Mono / Stereo Audio Amplifier with

Microphone Pre-Amplifier and EMU Interface

Features

Description

The FAN3800 is a low-cost solution that integrates the

many discrete parts currently used in stereo headset

applications. It provides mono / stereo speaker drivers

and a complete microphone interface. Additionally, the

FAN3800 allows headset detection and identification

through a 5-pin, enhanced mini-USB (EMU) bus.

Manual and remote send-end switching is supported.

Regulated positive supply

Negative supply generator allows ground-centered

output swing

Dual speaker drivers with mono/stereo switch

capability

Capable of driving 16mW_RMSper channel

Complete external microphone interface

The FAN3800 speaker drivers are designed to operate

with a ground-centered output signal. This allows

removal of large and expensive DC blocking capacitors.

In addition, it allows interfacing with externally powered

speakers. The speaker drivers are capable of driving up

to 16mW_RMSper channel.

Enhanced mini-USB bus detection and interface

circuitry

Manual and remote send-end switch interface

Pop and click suppression

FAN3800 delivers a complete solution for interfacing an

external microphone. The microphone interface

provides a regulated, high PSRR supply, differential

input sense to single-ended output driver amplifiers,

and output muting. Gain is fixed at 36dB and can be

attenuated externally with a resistor divider network.

microphone output to the D+ output. When activated,

the speakers switch from stereo to mono mode, both

driven by the D- input. Pop and click noise is minimized

during switching. Send-end information can be

generated manually through an external switch or

through the EMU bus interface.
