TK10416

DYNAMIC SPEAKER DRIVE AMPLIFIER

FEATURES

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

■ Very Low Supply Current

■ Very Low Standby Current

■ Miniature Package (SOT23L-6)

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

■ Needs No Output Coupling Capacitor

DESCRIPTION

The TK10416M is a very low operating voltage and current
audio power amplifier to drive dynamic speakers.

The TK10416M drives the speaker directly, because the
device has a differential output that does not need an
output coupling capacitor.

APPLICATIONS

■ Speaker Driver for Portable Equipment

■ Headphone Driver

■ Toys

ref/Standby

The voltage gain is adjustable by two external resistors.
The TK10416M is available in the very small SOT23L-6

surface mount package.
The small package in conjunction with few external

components save printed circuit board space.
