| TK10415 CERAMIC SPEAKER DRIVE AMPLIFIER FEATURES s s s s s 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 A) Miniature Package (SOT23L-6) Very Large Output Voltage (VOUT(MAX) = 1.7 Vrms @ VCC = 2.4 V, RL = 620 ) s Very Small Total Harmonic Distortion (THD = 0.1 % @ VOUT = 0.8 Vrms) s Needs No Output Coupling Capacitor APPLICATIONS s Speaker Driver for Portable Equipment s Headphone Driver s Toys and Games DESCRIPTION The TK10415M is a very low operating voltage and current audio power amplifier to drive ceramic speakers. TK10415 VOUT 1 VIN 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.
