The TPA4860 is a bridge-tied load (BTL) audio power amplifier capable of delivering 1 W of continuous average power into an 8-load at 0.4 % THD+N from a 5-V power supply in voiceband frequencies (f < 5 kHz). A BTL configuration eliminates the need for external coupling capacitors on the output in most applications. Gain is externally configured by means of two resistors and does not require compensation for settings of 2 to 20. Features of this amplifier are a shutdown function for power-sensitive applications as well as headphone interface logic that mutes the output when the speaker drive is not required. Internal thermal and short-circuit protection increases device reliability. It also includes headphone interface logic circuitry to facilitate headphone applications. The amplifier is available in a 16-pin SOIC surface-mount package that reduces board space and facilitates automated assembly.

The TPA5050 accepts a single serial audio input, buffers the data for a selectable period of time, and outputs the delayed audio data on a single serial output. One device allows delay of up to 170 ms/ch (fs = 48 kHz) to synchronize the audio stream to the video stream in systems with complex video processing algorithms. If more delay is needed, the devices can be connected in series.

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-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 buffer and volume control gain stages that are set by dc voltages. The buffer has a differential input and 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 the BTL mode and is 6 dB lower in the 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 the 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. 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 TPA6010A4 to operate at full power into 8-loads at ambient temperatures of 85°C.

The TPA6011A4 is a stereo audio power amplifier that drives 3 W/channel of continuous RMS power into a 3-load. Advanced dc volume control minimizes external components and allows BTL (speaker) volume control and SE (headphone) volume control. Notebook and pocket PCs benefit from the integrated feature set that minimizes external components without sacrificing functionality. To simplify design, the speaker volume level is adjusted by applying a dc voltage to the VOLUME terminal. Likewise, the delta between speaker volume and headphone volume can be adjusted by applying a dc voltage to the SEDIFF terminal. To avoid an unexpected high volume level through the headphones, a third terminal, SEMAX, limits the headphone volume level when a dc voltage is applied. Finally, to ensure a smooth transition between active and shutdown modes, a fade mode ramps the volume up and down.
