TPA03122.6-W, stereo, analog input Class-AB audio amplifier & 21.6 dB gain setting | Amplifiers | 1 | Active | The TPA0312 is a stereo audio power amplifier in a 24-pin TSSOP thermally enhanced package capable of delivering 2.6 W of continuous RMS power per channel into 3-speakers, the TPA0312 has less than 0.8% THD+N across its specified frequency range.
Included within this device is integrated depop circuitry that virtually eliminates transients that cause noise in the speakers.
Amplifier gain is internally configured and controlled by way of two terminals (GAIN0 and GAIN1). BTL gain settings of 6 dB, 10 dB, 15.6 dB, and 21.6 dB (inverting) are provided, while SE gain is always configured as 4.1 dB (inverting) for headphone drive. 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 SE or 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 TPA0312 automatically switches into SE mode when the SE/BTL\ input is activated, and this reduces the gain to 4.1 dB.
The TPA0312 consumes only 6 mA of supply current during normal operation. A miserly shutdown mode reduces the supply current to less than 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 readily realized in multilayer PCB applications. This allows the TPA0312 to operate at full power into 8-loads at an ambient temperature of 85°C.

TPA2000D1-Q1Automotive, 2-W, analog input mono Class-D audio amplifier | Evaluation Boards | 9 | Active | The TPA2000D2 is the third generation 5-V class-D amplifier from Texas Instruments. Improvements to previous generation devices include: lower supply current, lower noise floor, better efficiency, four different gain settings, smaller packaging, and fewer external components. The most significant advancement with this device is its modulation scheme that allows the amplifier to operate without the output filter. Eliminating the output filter saves the user approximately 30% in system cost and 75% in PCB area.
The TPA2000D2 is a monolithic class-D power IC stereo audio amplifier, using the high switching speed of power MOSFET transistors. These transistors reproduce the analog signal through high-frequency switching of the output stage. The TPA2000D2 is configured as a bridge-tied load (BTL) amplifier capable of delivering greater than 2 W of continuous average power into a 3-load at 1 kHz, the typical THD+N is less than 0.08%.
A BTL configuration eliminates the need for external coupling capacitors on the output. Low supply current of 8 mA makes the device ideal for battery-powered applications. Protection circuitry increases device reliability: thermal, over-current, and under-voltage shutdown.
Efficient class-D modulation enables the TPA2000D2 to operate at full power into 3-loads at an ambient temperature of 85°C.
