TPA2001D1

illustrate

The TPA2001D1 is a 1-W mono bridged load (BTL) Class D amplifier designed to drive a speaker of at least 8-Impedance. The amplifier uses TI's third-generation modulation technology to improve efficiency and signal-to-noise ratio. It also allows devices to connect directly to speakers typically associated with Class D amplifiers without the use of LC output filters (electromagnetic interference must be shielded at the system level). These features make it ideal for using the device when high efficiency is required, extending the battery life of the device.

The amplifier's gain control is controlled by two inputs, GAIN1 and GAIN0. This makes the amplifier a gain configuration for 6, 12, 18 and 23.
