DUAL 100mW AUDIO POWER
AMPLIFIER WITH STANDBY
MODE
CMOS IC
DESCRIPTION
The UTC S486 is a dual power amplifier capable of delivering
typically 100mW per channel of continuous average power to an
8Ω load with 0.1% THD+N using a 5V power supply.
The UTC S486 features an externally controlled, low-power
consumption shutdown mode. The UTC S486 exhibit a low
quiescent current of typically 1.8mA, allowing usage in portable
applications.
The unity-gain stable UTC S486 can be configured by external
gain-setting resistors.
FEATURES
* Operating voltage range VCC=2V ~ 5.5V
* Output power:
- 102mW @5V into 16Ω with 0.1% THD+N max (1kHz)
* Shutdown mode available
* Low current consumption: 2.5mA max
* Click and pop reduction circuitry
* Unity-gain stable
* Short circuit protected
