TPA3106D1VFPR Datasheet PDF - TI

●The TPA3106D1VFPR is a 40W Mono Class-D Audio Power Amplifier for driving bridged-tied stereo speaker. The TPA3106D1 can drive stereo speakers as low as 4. The high efficiency ~92% of the TPA3106D1 eliminates the need for an external heat sink when playing music. The gain of the amplifier is controlled by two gain select pins. The gain selections are 20, 26, 32, 36dB. The outputs are fully protected against shorts to GND, VCC and output-to-output shorts with an auto recovery feature and monitor output. It uses a modulation scheme that still has each output switching from 0 to the supply voltage. However, OUTP and OUTN are now in phase with each other with no input. The duty cycle of OUTP is greater than 50% and OUTN is less than 50% for positive output voltages.

● 40W into an 8R load from a 25V supply

● Efficient Class-D operation eliminates the need for heat sinks

● Four selectable, fixed gain settings

● Differential inputs

● Thermal and short-circuit protection with auto recovery feature

● Clock output for synchronization with multiple Class-D devices

● Green product and no Sb/Br

●This device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
