DESCRIPTION

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-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.

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.
