6.5-W MONO CLASS-D AUDIO POWER AMPLIFIER
6.5 W Into 8- Load From 12-V Supply
(10% THD+N)
The TPA3007D1 is a 6.5-W mono bridge-tied load
(BTL) class-D audio power
amplifier
with
high
Short Circuit Protection (Short to V
CC, Short to
efficiency, eliminating the need for heat sinks. The
GND, Short Between Outputs)
TPA3007D1 can drive 8-
speakers with only a
Third-Generation Modulation Technique:
ferrite bead filter required to reduce EMI.
–
Replaces Large LC Filter With Small,
The gain of the amplifier is controlled by two input
Low-Cost Ferrite Bead Filter in Most
terminals,
GAIN1
and
GAIN0.
This
allows
the
Applications
amplifier to be configured for a gain of 12, 18, 23.6,
–
Improved Efficiency
and 36 dB. The differential input stage provides high
common mode rejection and improved power supply
–
Improved SNR
rejection.
Low Supply Current ... mA Typ at 12 V
The amplifier also includes "de-pop" circuitry to

LCD Monitors/TVs
The TPA3007D1 is available in the 24-pin TSSOP
package (PW) and does not require an external heat
