STEVAL-CCA044V1
160 W + 160 W dual BTL class-D audio amplifier demonstration
board based on the TDA7498E
Data brief
Features
■ High output-power capability:
– 2 x 160 W / 4 Ω at 36 V, 1 KHz, THD = 10%
– 1 x 220 W / 4 Ω at 36 V, 1 KHz, THD = 10%
■ Wide-range, single supply operation (14 V-
36 V)
■ High efficiency (η = 85%)
■ Four selectable, fixed gain settings
(23.6 dB, 29.6 dB,33.1 dB and 35.6 dB)
■ Differential inputs to minimize common-mode
noise
■ Standby and mute features
■ Short-circuit and thermal overload protection
■ Externally synchronizable
■ RoHS compliant
Description
The STEVAL-CCA044V1 demonstration board is
designed for the TDA7498E high power dual BTL
class-D audio amplifier.
Thanks to its high efficiency, the device
assembled in the PSSO36 (slug-down) package
is capable of dissipating heat without a heatsink.
Jumpers on the board allow the configuration of
the amplifier in order to verify all the features as
single-ended or differential input, fixed gain
settings.
Microswitches are also provided to enable the
standby and mute functions.
