TPA0103

description
The TPA0103 is a 3-channel audio power amplifier in a 24-pin TSSOP thermal package primarily targeted at
desktop PC or notebook applications. The left/right (L/R) channel outputs are single ended (SE) and capable
of delivering 500 mW of continuous RMS power per channel into 4-
loads. The center channel output is a
bridged tied load (BTL) configuration for delivering maximum output power from PC power supplies. Combining
the SE line drivers and high power center channel amplifiers in a single TSSOP package simplifies design and
frees up board space for other features. Full power distortion levels of less than 0.25% THD+N into 4-
loads
from a 5-V supply voltage are typical. Low-voltage application are also well served by the TPA0103 providing
800 mW to the center channel into 4-
loads with a 3.3-V supply voltage.
Amplifier gain is externally configured by means of two resistors per input channel and does not require external
compensation for settings of 1 to 10. A two channel input MUX circuit is integrated on the L/R channel inputs
to allow two sets of stereo inputs to the amplifier. In the typical application, the center channel amplifier is driven
from a mix of the L/R inputs to produce a monaural representation of the stereo signal. The center channel
amplifier can be shut down independently of the L/R output for speaker muting in headphone applications. The
TPA0103 also features a full shutdown function for power sensitive applications holding the bias current
to 5
A.
The PowerPAD package (PWP) delivers a level of thermal performance that was previously achievable only
in TO-220-type packages. Thermal impedances of less than 35
°C/W are readily realized in multilayer PCB
applications. This allows the TPA0103 to operate at full power at ambient temperature of up to 85
°C.
