DESCRIPTION
The TPA6010A4 is a stereo audio power amplifier in a 28-pin TSSOP thermally enhanced package capable of
delivering 2.7 W of continuous RMS output power into 3-鈩?loads. When driving 1 W into 8-鈩?speakers, the
TPA6010A4 has less than 0.22% THD+N across its specified frequency range.
The TPA6010A4 has several features optimized for notebook PCs including bass boost, docking station outputs,
dc volume control, and dc gain control.
The TPA6010A4 has a buffer and volume control gain stage that are set by dc voltages. The buffer has a
differential input and a differential output. The gain of the buffer, which is controlled by the dc voltage on the
BUFFGAIN terminal, is adjustable from -46 dB to 14 dB. The docking station output is 6 dB lower than the buffer
gain because the buffer has a differential output and the docking station output is taken from just one of the
buffer outputs. The volume control amplifier is adjustable from -34 dB to 20 dB in BTL mode and is 6 dB lower in
SE mode. The volume control stage is adjustable by dc voltage on the VOLUME terminal. The amplifier gain
from input-to-speaker is the sum of the volume control and the buffer gain. The input-to-speaker gain is
adjustable from -86 dB to 34 dB in BTL mode and -92 dB to 28 dB in the SE mode.
The bass boost of the amplifier sums the right and left inputs, adds gain, filters out the high frequencies, and
then adds the bass boost signal back into the output power amplifier. The frequency of the bass boost is
adjusted by adding an RC filter from BBOUT to BBIN. The gain of the bass boost is set to 12 dB if the same
bass is present in both the right and left channels. If the bass is present in just one of the channels, the gain of
the bass is set to 9.5 dB. The gain can be reduced by adding a voltage divider from BBIN to BBOUT. If not using
the bass boost, pull the BBENABLE pin low.
