DESCRIPTION

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-鈩?or 8-鈩?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 depop circuitry to reduce the

amount of pop at power-up and when cycling

SHUTDOWN.

The TPA3001D1 is available in the 24-pin thermally

enhanced TSSOP package (PWP) which eliminates the

need for an external heat sink.

APPLICATIONS
