Alternate Parts for TDA7493
This table gives cross-reference parts and alternative options found for TDA7493. The Form Fit Function (FFF) tab will give you the options that are more likely to serve as direct pin-to-pin alternates or drop-in parts. The Functional Equivalents tab will give you options that are likely to match the same function of TDA7493, but it may not fit your design. Always verify details of parts you are evaluating, as these parts are offered as suggestions for what you are looking for and are not guaranteed.
TDA7493 Frequently Asked Questions (FAQ)
-
STMicroelectronics recommends using a 10uF ceramic capacitor and a 100nF ceramic capacitor in parallel, placed as close as possible to the power supply pins (VP and VN) to ensure stable operation.
-
The gain of the TDA7493 can be configured by connecting a resistor (Rg) between the GAIN pin and the negative power supply (VN). The gain is calculated as 20 dB + (Rg/1.2 kΩ).
-
The maximum power dissipation of the TDA7493 is 20W, assuming a junction temperature of 150°C and a thermal resistance of 2.5°C/W. However, this value can be derated based on the ambient temperature and the thermal design of the system.
-
The TDA7493 has a built-in thermal shutdown feature that turns off the amplifier if the junction temperature exceeds 150°C. Additionally, a heatsink can be used to dissipate heat, and the system design should ensure good airflow and thermal management.
-
STMicroelectronics recommends a 4-layer PCB with a solid ground plane, and the power supply lines should be routed away from the signal lines to minimize noise and electromagnetic interference (EMI).
