TOKO TK10416MTL Datasheet
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.
