The TPA3007D1 is a 6.5-W mono bridge-tied load (BTL) class-D audio power amplifier with high efficiency, eliminating the need for heat sinks. The TPA3007D1 can drive 8- 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.

The amplifier also includes "de-pop" circuitry to reduce the amount of pop at power-up and when cycling SHUTDOWN.

The TPA3007D1 is available in the 24-pin TSSOP package (PW) and does not require an external heat sink.
