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.
