TPA2001D1 - 1-W FILTERLESS MONO CLASS-D AUDIO POWER AMPLIFIER
The TPA2001D1 is a 1-W mono bridge-tied-load (BTL) class-D amplifier designed to drive a speaker with at least 8-Ω impedance.
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

TPA2001D1 Features
* make the device ideal for use in devices where high-efficiency is needed to extend battery run time. The gain of the amplifier is controlled by two input terminals, GAIN1, and GAIN0. This allows the amplifier to be configured for a gain of 6, 12, 18, and 23.5 dB. The differential input terminals are
