5 W + 5 WD Class Audio Amplifier Demonstration Board Based on TDA7491LP

STEVAL-CCA029V1

Overview

The STEVAL-CCA029V1 demonstration board is designed for the evaluation of the TDA7491LP dual BTL class-D audio amplifier.

Due 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 the configuration of 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.

Main features

5 W + 5 W continuous output power at THD = 10%, RL = 8 Ω, VCC = 9 V
5 W + 5 W continuous output power at THD = 10%, RL = 4 Ω, VCC = 6.5 V
Power supply voltage range: 5 V to 14 V
Number of channels: 2 BTL (bridge tied load) stereo
Load impedance: 4 Ω to 8 Ω
Gain settings: 20 dB, 26 dB, 30 dB, 32 dB
Undervoltage protection (UVP): 4 V
External synchronization
RoHS compliant

Measurement issues for transformer groups
For example, if the connection of a transformer group is Yd11, and we only know that the connection of the primary winding and the secondary winding is star and triangle, that is, we only know Yd, how
Infrared carrier frequency
For infrared communication, the transmission rate should reach 1Mb/s. I want to raise the carrier frequency of infrared transmission and reception to 20MHZ. Has anyone succeeded? Is it feasible? I use

I recently applied for an embedded software engineer position. Since most people know about common technical knowledge, I will not describe it here. Instead, I have sorted out other interview experien
Is the code compiled by VDSP very inefficient?
What do you think of the efficiency of VDSP's compiled code? Why do I feel that the efficiency of C language compiled code is very low? Although compiler optimization is enabled, there are few paralle
