  • Page 16 3. TPA3001D1 The TPA3001D1 is a 20-W mono bridge-tied load (BTL) class-D audio power amplifier with high efficiency, eliminating the need for heat sinks. The TPA3001D1 can drive 4-Ω or 8-Ω speakers with only a ferrite bead filter required to reduce EMI. The gain of the amplifier is controlled by two input terminals,GAIN1 and GAIN0.
