TPA2000D1EVM 描述
The TPA2000D1 is a 2-W mono bridge-tied-load (BTL) class-D amplifier designed to drive a 4 Ohm speaker. The amplifier uses TI's third generation modulation technique, which results in improved efficiency and SNR. It also allows the device to be connected directly to the speaker without the use of the LC output filter commonly associated with class-D amplifiers. These features make the device ideal for use in applications where high-efficiency is needed to extend battery run time.
