EUA5544

Class AB Stereo Headphone Driver

with Shutdown

DESCRIPTION

FEATURES

The EUA5544 is pin compatible with the BH3541/4, and

No Switch On/Off Clicks

functionally compatible with the TPA611× series and

Wide Power Supply Operation 2.5V– 6V

Mute Function Compatibility

High Signal-to-Noise Ratio

LM488 ×series. As the EUA5544 contains advanced

depop circuitry which eliminates pops & clicks during

shutdown-on and shutdown-off, it can reduces a capacitor

and resistor compared to Mute solution of other devices.

The EUA5544 features an advantage of low-power

consumption shutdown mode, activated by driving the

shutdown pin with logic low. And it also allows fast

turn-on with 1µF bypass capacitor (C_B).

Low Distortion

Large Output Voltage Swing

Excellent Power Supply Ripple Rejection

High Crosstalk Immunity＞85dB

Low Quiescent Current

Ultra-low Shutdown Current …0.02µA typical

Short-circuit Protection

The EUA5544 is an integrated class AB stereo headphone

amplifier capable of delivering 68mW per channel of

continuous average power into a 16Ω load or 35mW per

channel into a 32Ω load from a 5V power supply. It also

can operate from a 3V supply, capable of delivering 24

mW into a 32Ω load.

Integrated Voltage Divider (V_DD/2) to Eliminate

External Resistors

Available in SOP-8

RoHS Compliant and 100% Lead (Pb)-Free

The EUA5544 further integrates a voltage divider inside

the chip. Thus, the external resistors can be eliminated.

The EUA5544 has a fixed gain of 6dB so that external

gain setting is unnecessary.

APPLICATIONS

Headphone Amplifier for CD-ROMs

Portable Audio Equipment
