0.1µA(typ.)

The OCP7190 is an audio power amplifier primarily

designed for demanding applications in mobile

phones and other portable communication device

applications. It is capable of delivering 1 watt of

continuous average power to an 8Ω BTL load with less

than 1% distortion (THD+N) from a 5VDC power

supply.

Audio power amplifiers were designed specifically to

provide high quality output power with a minimal

amount of external components. The OCP7190 does

not require output coupling capacitors or bootstrap

capacitors, and therefore is ideally suited for mobile

phone and other low voltage applications where

minimal power consumption is a primary requirement.

Features

Available in space-saving packages: micro SMD,

MSOP

Ultra low current shutdown mode

BTL output can drive capacitive loads

Improved pop and click circuitry eliminates noises

during turn-on and turn-off transitions

2.2V - 5.5V operation

No output coupling capacitors, snubber networks

or bootstrap capacitors required

Thermal shutdown protection

Unity-gain stable

The OCP7190 features a low-power consumption

shutdown mode, which is achieved by driving the

shutdown pin with logic low. Additionally, the

OCP7190 features an internal thermal shutdown

protection mechanism.

External gain configuration capability

The OCP7190 contains advanced pop and click

circuitry which eliminates noises which would

otherwise occur during turn-on and turn-off transitions.

The OCP7190 is unity-gain stable and can be

configured by external gain-setting resistors.

Applications

Mobile Phones

PDA

Portable electronic devices
