TPA3250 Bluetooth (130W+130W)
Product introduction:
The TPA3250 is a Class D power amplifier.
The device operates from a 32 V supply and can drive up to 2 W x 130 W peak into a 4 Ω load or 2 W x 70 W continuous into an 8 Ω load with a 2 VRMS analog input interface, which can be seamlessly matched with high-performance DACs such as TI PCM5242.
In addition to excellent audio performance, the TPA3250 also achieves high power efficiency and sub-1 W power stage no-load consumption. This is achieved by using a 60 mΩ MOSFET and an optimized gate driver scheme with much lower no-load losses than typical discrete devices.
Basic parameters:
1. Working method: Class D
2. Quiescent current: 50mA

4. Rated output power: 2*130W
5. Frequency response: 20Hz to 20KHz
6. Working voltage: DC18V to DC32V
7. Maximum output current: 4A
8. Size: length 103* width 78* height 25MM
9. Weight: 0.1KG
Note:
1. The input signal of AUX 3.5 cannot exceed 1V amplitude, and it will cause saturation distortion if greater than 1V
2. There are three input methods of Bluetooth U disk AUX, only one of which can be selected for use
