DESCRIPTION

The TPA3007D1 is a 6.5-W mono bridge-tied load

(BTL) class-D audio power amplifier with high ef-

ficiency, eliminating the need for heat sinks. The

TPA3007D1 can drive 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 ampli-

fier to be configured for a gain of 12, 18, 23.6, and 36

dB. The differential input stage provides high com-

mon 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 TPA3007D1 is available in the 24-pin TSSOP

package (PW) and does not require an external heat

sink.
