Preliminary

EUA4992

2W Stereo Audio Power Amplifier

DESCRIPTION

FEATURES

The EUA4992 is a dual bridge-connected audio power

amplifier designed for portable communication device

applications such as mobile phone applications. The

EUA4992 is capable of delivering 1.3W of continuous

average power to an 8Ω BTL and with less than 1%

distortion (THD+N) from a 5.0V power supply, and

540mW to an 8Ω BTL load from a 3.3V power supply.

Output Power at 1% THD+N, V_DD=5V

-- 2W/CH (typ) into a 4ꢀ Load

-- 1.3W/CH (typ) into a 8ꢀ Load

Output Power at 1% THD+N, V_DD=3.3V

-- 0.84W/CH (typ) into a 4ꢀ Load

-- 0.54W/CH (typ) into a 8ꢀ Load

Shutdown Current 0.04µA (typ)

Supply Voltage Range 2.5V to 5.5V

Suppress “ click and pop”

Thermal Shutdown Protection Circuitry

Micro Power Shutdown Mode

TQFN-16 (3mm×3mm) Package

RoHS compliant and 100% lead(Pb)-free

The EUA4992 provides high quality audio while requiring

few external components and minimal power consumption.

It features a low-power shutdown mode, which is achieved

by driving the

pin with logic low.

SHUTDOWN

The EUA4992 contains circuitry to prevent from ”pop and

click” noise that would otherwise occur during turn-on and

turn-off transitions.

For maximum flexibility, the EUA4992 provides an

externally controlled gain (with resistors), as well as an

externally controlled turn-on and turn-off times (with the

bypass capacitor).

APPLICATIONS

The EUA4992 is available in a 3mm×3mm TQFN package.

Cell phones, PDA, MP4,PMP

Portable and Desktop Computers

Desktops audio System

Multimedia Monitors
