DESCRIPTION
The TPA3000D1 is a 17-W mono bridge-tied load (BTL)
filter-free class-D audio power amplifier with high
efficiency, eliminating the need for heatsinks. The
TPA3000D1 is designed to drive speakers without an
output filter.
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 turnon pop at power-up and when cycling
SHUTDOWN.
The TPA3000D1 is available in the 24-pin thermally
enhanced TSSOP package (PWP) which eliminates the
need for an external heat sink when playing music.
