POWER AMPLIFIER

FEATURES

■ Very Wide Operating Voltage (VCC = 1.8 to 5.5 V)

■ Very Low Supply Current

■ Very Low Standby Current

■ Miniature Package (SOT23L-8)

■ Adjustable Voltage Gain (VG1 = 0 to 40 dB)

■ Active High On/Off Control

DESCRIPTION

The TK10417M is a very low operating voltage and current audio power amplifier. The device is in the “on” state when the standby pin is pulled to a logic high level.

The TK10417M is available in the very small SOT23L-8 surface mount package.

APPLICATIONS

■ Speaker Driver for Portable Equipment

■ Headphone Driver

■ Toys
