EUA4890
1 Watt Audio Power Amplifier
DESCRIPTION
The EUA4890 is an audio power amplifier designed for
portable communication device applications such as
mobile phone applications. The EUA4890 is capable of
delivering 1.0W of continuous average power to an 8
BTL and with less than 1% distortion (THD+N) from a
5.0V power supply, and 350mW to a 8BTL load from a
3V power supply.
The EUA4890 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 SHUTDOWN pin with logic low.
The EUA4890 contains circuitry to prevent from ”pop and
click” noise that would otherwise occur during turn-on and
turn-off transitions.
For maximum flexibility, the EUA4890 provides an
externally controlled gain (with resistors), as well as an
externally controlled turn-on and turn-off times (with the
bypass capacitor).
The EUA4890 is available in a MSOP-8 , 3mm×3mm DFN
package.
FEATURES
z 2.5-5.5V operation
z 65dB PSRR at 217Hz, VDD=5V
z 0.1µA ultra low current shutdown mode
z Improved pop & click circuitry
z No output coupling capacitors, snubber networks or
bootstrap capacitors required
z Thermal shutdown protection
z Unity-gain stable
z External gain configuration capability
z BTL output can drive capacitive loads
z RoHS compliant and 100% lead(Pb)-free
APPLICATIONS
z Mobile Phones
z PDAs
z Portable electronic devices
