TPA3122 Datasheet PDF

●The TPA3122D2N is a 15W stereo class D audio power amplifier with SE outputs in 20pin DIP package. This audio power amplifier is used for driving stereo single ended speakers or mono bridge tied load. The TPA3122D2 can drive stereo speakers as low as 4ohm. The efficiency of this device eliminates need for an external heat sink when playing music. The gain of amplifier is controlled by two gain select pins. The gain selections are 20dB, 26dB, 32dB and 36dB.

● 10W/ch into an 4ohm load from 17V supply

● 15W/ch into an 8ohm load from 28V supply

● Supply voltage range from 10V to 30V

● Internal oscillator (no external components required)

● Single ended analogue inputs

● Thermal and short circuit protection with auto recovery feature

● Operating free air temperature range from -40°C to 85°C

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