60mW, Capfree, Stereo Headphone Amplifier

The ISL99202 is a stereo, capfree headphone amplifier. The

wide operating voltage of 2.4V to 5.5V makes it versatile

enough to be used in mobile battery powered applications

powered by 2 AA or Single cell Li-Ion batteries as well as

3.3/5V power supply available notebook computers.

The ISL99202 has robust RF immunity, which makes it

ideally suited for today’s mobile applications.

It has audiophile quality SNR and THD specifications and

Click/Pop suppression.

The ISL99202 comes with Comprehensive Protection

features, which include undervoltage and short-circuit

protection and thermal shutdown.

The ISL99202 lowest power consumption in the industry is

achieved by low I

qq

and current shutdown.

The product is available in 12 Ld TQFN.

Features

• Supports 16Ω to 600Ω speaker impedance

• Ground referenced: No output coupling capacitors

• Audiophile quality sound THD of 0.01%, SNR of 102dB

• PSRR < -90dB, no need for LDO

• Wide operating voltage of 2.4V to 5.5V

• < 3mA quiescent current and 0.1µA shutdown current

• State of the art pop and click suppression

• Pb-Free (RoHS Compliant)

Applications

• Mobile phones

• MP3 players

for details on reel specifications.

Evaluation Board

2. These Intersil Pb-free plastic packaged products employ special Pb-free material sets, molding compounds/die attach materials, and 100% matte

tin plate plus anneal (e3 termination finish, which is RoHS compliant and compatible with both SnPb and Pb-free soldering operations). Intersil

Pb-free products are MSL classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-20.
