INTEGRATED CIRCUITS INC.--- aP4890K
aP4890K --- 1.4 Watt Audio Power Amplifier
FEATURES :
2.5V~5.5V Power supply.
Thermal shutdown Protection.
Low current shutdown mode
No output capacitors and networks or bootstrap
capacitors required
Low noise during turn-on and turn-off transitions
Shutdown pin high active.
GENERAL DESCRIPTION :
The AP4890K is a 1.4 Watt audio power amplifier. And the AP4890K primarily designed for high
Quality application in other portable communication device.
It is capable of driving 8Ω speaker load at a continuous average output of 1.4W / 10% distortion
(THD+N) from a 5.0V power supply. A feature of the AP4890K amplifier to switch BTL mode. And
the AP4890K audio amplifier features low power consumption shutdown mode. It is achieved by
driving the shutdown pin with logic high. Besides the AP4890K has an internal thermal shutdown
protection feature.
The AP4890K amplifier was designed specifically to provide high quality output power with a
minimal amount of external components. The AP4890K does not require output capacitors, and
the AP4890K is ideally suited for other low voltage applications or portable electronic devices
where minimal power consumption is a primary requirement.
APPLICATION :
Portable electronic devices
Mobile Phones
