STEVAL-CCA028V1

10 W + 10 W class-D audio amplifier demonstration board

based on the TDA7491P

Data brief

Features

■ 10 W +10 W continuous output power at THD

= 10%, R = 6 Ω, V = 11 V

■ 9.5 W + 9.5 W continuous output power at THD

= 10%, R = 8 Ω, V = 12 V

■ Wide-range single-supply operation (5-18 V)

■ High efficiency (η= 90 %)

■ Four selectable, fixed gain settings

(20 dB, 26 dB, 30 dB and 32 dB)

■ Differential inputs to minimize common-mode

noise

■ Filterless operation

STEVAL-CCA028V1

■ Standby and mute features

■ Short-circuit and thermal overload protections

■ Externally synchronizable

■ RoHS compliant

Description

The STEVAL-CCA028V1 demonstration board is

designed for the TDA7491P 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 any

heatsink.

Jumpers on the board allow configuring the

amplifier in order to verify all the features as

single-ended or differential inputs, fixed gain

settings.

Microswitches are also provided to enable the

standby and mute functions.
