The TPA0242 is a stereo audio power amplifier in a 24-pin TSSOP thermally-enhanced package capable of
delivering 2.8 W of continuous RMS power per channel into 3-
Ω loads.
This device minimizes the number of external components needed, which simplifies the design and frees up
board space for other features. When driving 1 W into 8-
Ω speakers, the TPA0242 has less than 0.22% THD+N
across its specified frequency range.
The integrated depop circuitry virtually eliminates transients that cause noise in the speakers.
Amplifier gain is controlled by a dc voltage input on the VOLUME terminal. There are 31 discrete steps covering
the range of 20 dB (maximum volume setting) to -40 dB (minimum volume setting) in 2 dB steps. When the
VOLUME terminal exceeds 3.54 V, the device is muted. An internal input MUX allows two sets of stereo inputs to
the amplifier. The HP/LINE terminal allows the user to select which MUX input is active regardless of whether the
amplifier is in single-ended (SE) or bridge-tied load (BTL) mode. In notebook applications, where internal
speakers are driven as BTL and the line outputs (often headphone drive) are required to be SE, the TPA0242
automatically switches into SE mode when the SE/BTL input is activated, and this effectively reduces the gain by
6 dB.
The TPA0242 consumes only 20 mA of supply current during normal operation. A miserly shutdown mode
reduces the supply current to 150 µA.
The PowerPAD package (PWP) delivers a level of thermal performance that was previously achievable only in
TO-220-type packages. Thermal impedances of approximately 35
°C/W are truly realized in multilayer PCB
applications. This allows the TPA0242 to operate at full power into 8-
Ω loads at ambient temperatures of 85°C.

Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
