STEVAL-CCA042V1

20 W + 20 W dual BTL class-D audio amplifier demonstration board

based on the TDA7491HV

Data brief

Features

■ 20 W +20 W continuous output power at

THD = 10%, R_L= 8 Ω, V_CC= 18 V

■ 9.5 W + 9.5 W continuous output power at

THD = 10%, R_L= 8 Ω, V_CC= 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

■ Standby and mute features

■ Short-circuit and thermal overload protections

■ Externally synchronizable

■ RoHS compliant

Description

The STEVAL-CCA042V1 demonstration board is

designed for the TDA7491HV 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 configuration of the

amplifier 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
