description
The TPA6100A2 is a stereo audio power amplifier packaged in either an 8-pinSOIC package or an 8-pin MSOP
package capable of delivering 50 mW of continuous RMS power per channel into 16-
loads. Amplifier gain
is externally configured by a means of three resistors per input channel and does not require external
compensation for settings of 1 to 10.
The TPA6100A2 is optimized for battery applications because of its low supply current, shutdown current, and
THD+N. To obtain the low-supply voltage range, the TPA6100A2 biases BYPASS to V
DD
/4. A resistor with a
resistance equal to R
F
must be added from the inputs to ground to allow the output to be biased at V
DD
/2.
When driving a 16-
load with 45-mW output power from 3.3 V, THD+N is 0.04% at 1 kHz, and less than 0.2%
across the audio band of 20 Hz to 20 kHz. For 28 mW into 32-
loads, the THD+N is reduced to less than 0.03%
at 1 kHz, and is less than 0.2% across the audio band of 20 Hz to 20 kHz.
