Product Summary

The TPA3001D1PWPR is a 20-W mono bridge-tied load (BTL) class-D audio power amplifier with high efficiency, eliminating the need for heat sinks. The TPA3001D1PWPR 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. This allows the amplifier to be configured for a gain of 12, 18, 23.6, and 36 dB. The differential input stage provides high common mode rejection and improved power supply rejection.
