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

Note 1: Power dissipation is 400 mW in free air. Derate at 3.2 mW/°C for operation above 25 °C.
Note 2: Power dissipation is 600 mW when mounted. Derate at 4.8 mW/°C for operation above 25 °C. Maximum junction temperature is limited
to 150 °C.
