Details
The TPA0172 is a stereo audio power amplifier in a 24-pin TSSOP thermally enhanced package capable of delivering 2 W of continuous RMS power per channel into 4- loads. This device utilizes the I2C bus to control its functionality, which minimizes the number of external components needed, simplifies the design, and frees up board space for other features. When driving 1 W into 8- speakers, the TPA0172 has less than 0.2% THD+N from 20 Hz to 20 kHz.
Included within this device is integrated depop circuitry that virtually eliminates transients that cause noise in the speakers at power up, power down, and while transitioning in and out of shutdown mode.
The overall gain of the amplifier is controlled digitally by the volume control registers which are programmed via the I2C interface. At power up, the amplifier defaults to -60 dB in BTL mode, or -66 dB in SE mode. There are four registers that contain the gains: left BTL, right BTL, left SE, and right SE. Each register contains six bits, which allows 64 gain steps from -60 dB to 20 dB in 1.25-dB steps, and two bits that mute the amplifier.
The TPA0172 only consumes 6.5 mA of supply current during normal operation. A shutdown mode is included that reduces supply current to less than 15 uA.
The PowerPAD package (PWP) delivers a level of thermal performance that was previously achievable on TO-200-type packages. Thermal impedances of approximately 35°C/W are truly realized in multilayer PCB applications. This allows the TPA0172 to operate at full power into 8- loads at ambient temperatures of 85°C.
