DESCRIPTION

The TK10415M is a very low operating voltage and current audio power amplifier to drive ceramic speakers.

The TK10415M drives the speaker directly, because the device has a differential output that does not need an output coupling capacitor.

The voltage gain is adjustable by two external resistors.

The TK10415M is available in the very small SOT23L-6 surface mount package.

The small package in conjunction with few external components saves printed circuit board space.

FEATURES

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

■ Very Low Supply Current (ICC = 1.8 mA @ VCC= 2.4 V)

■ Very Low Standby Current (ISTBY = 0.1 µA)

■ Miniature Package (SOT23L-6)

■ Very Large Output Voltage (VOUT(MAX) = 1.7 Vrms @ VCC = 2.4 V, RL = 620 Ω)

■ Very Small Total Harmonic Distortion (THD = 0.1 % @ VOUT = 0.8 Vrms)

■ Needs No Output Coupling Capacitor

APPLICATIONS

■ Speaker Driver for Portable Equipment

■ Headphone Driver

■ Toys and Games
