Mono / Stereo Audio Amplifier

FAN3800 — Mono / Stereo Audio Amplifier with Microphone Pre-Amplifier and EMU Interface October 2007 FAN3800 — Mono / Stereo Audio Amplifier with Microphone Pre-Amplifier and EMU Interface Features ƒ ƒ ƒ ƒ ƒ ƒ ƒ ƒ ƒ ƒ ƒ Regulated positive supply Negative supply generator allows ground-centered output swing Dual speaker drivers with mono/stereo switch capability Capable of driving 16mW RMS per channel Complete external microphone interface Enhanced mini-USB bus detection and interface circuitry Manual and remote send-end switch interface Pop and click suppression Single 2.7V to 4.5V operation 2kV ESD (HBM) protection MLP 24-pin package 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. 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 RMS per channel. FAN3800 delivers a complete solution for interfacing an external microphone. The microphone interface provides a regulated, high PSRR supply, differential input sense to single-.
