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.
