TPA3125D2

The TPA3125D2 is a 10-W (per channel), efficient,class-D audio power amplifier for driving stereo speakers in a single-ended configuration; or, a mono speaker in a bridge-tied-load configuration. The TPA3125D2 can drive stereo speakers as low as 4 Ω . The efficiency of the TPA3125D2 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, and 36 dB.

Features of the TPA3125D2 are:(1)10-W/Ch (stereo SE) into an 8- Load From a 24-V Supply; (2)20-W/Ch (mono BTL) into an 8- Load from a 24-V Supply; (3)Operates From 10 V to 26 V; (4)Operates From +24 V LCD Backlight Supply; (5)Efficient Class-D Operation Eliminates Need for Heat Sinks; (6)Four Selectable, Fixed-Gain Settings; (7)Single-Ended Analog Inputs; (8)Thermal and Short-Circuit Protection With Auto Recovery; (9)20-Pin DIP Package; (10)Advanced Power-Off Pop Reduction.

The absolute maximum ratings of the TPA3125D2 can be summarized as:(1)Operating free-air temperature range :40°C to 85°C; (2)Operating junction temperature range:40°C to 150°C; (3)Storage temperature range :65°C to 150°C.If you want to know more information such as the electrical characteristics ,please download the datasheet in www.seekdatasheet.com .
