L15DX2 IRS2092 IRAUDAMP7S Class D Amplifier Finished Board

Finished board with IRS2092+IRFI4019H

The IRAUDAMP7 combines many key protection features including overcurrent protection, overvoltage protection, undervoltage protection, DC protection and overtemperature protection. Management functions include ±5V power supply for preamplifier analog signal processing and Class D gate drive stage-B reference +12V power supply (Vcc). The board's resistors are made of high-precision five-ring metal film resistors, imported high-quality audio. Special inductor, high precision dedicated 1% error chip resistor, high quality imported filter capacitor

IR-specified dedicated digital power discharge. Fully shielded structure, OFC oxygen-free copper leads, no radiation, low distortion. Ultra low impedance structure. It has obvious advantages over other toroidal inductors. True OFC wire, very small internal resistance, test as shown.

1. IRAUDAMP7S is designed in accordance with IR's official parts requirements. Military grade PCB requirements. 2. This amplifier is made of the original imported capacitor from Japan. Ncc nichicon SANYO production. There are first-class manufacturers direct channel supply, and some use of domestic inferior small capacitors are obviously different effects. 3. All crystal components use the original ONSEMI Ansonmei Fast Recovery Diode. Germany VISHAY Vishay Transistor, the chip components use YAGEO National Resistance. Japanese original electrolytic capacitors. And SANYO OSCON solid capacitors imported from Japan. ESR is many times smaller than a normal capacitor.

Summary of OS-CON

OS-CON is a low equivalent series resistance capacitor ★ The frequency characteristic of the impedance basically reaches the most satisfactory value. It is suitable for use as a decoupling capacitor for removing ripple noise, peak noise, digital noise, static noise, and noise from audio equipment. ★ Allows more ripple current to pass. Conversion current smoothing capacitor for miniaturized equipment. ★ can be quickly discharged Suitable for protection capacitors in high speed and high current circuits.

The IC uses the IRS2092, and the output MOSFET uses IR-specific digital FET-specific twin FETs. By providing a new IRFI4xxxH-117P series MOSFET half-bridge, IR improves the performance of Class D audio amplifiers. The integrated half-bridge package mode reduces the number of components by half and improves the layout of the PCB. In addition to the low on-resistance, this family of MOSFET half-bridges has optimized gate charge, parasitic diode reverse recovery and internal gate resistance. These have improved the performance and performance of Class D audio amplifiers, such as operating efficiency, total harmonic distortion and electromagnetic radiation. The typical on-resistance RDS(ON) of IRFI4xxxH-117P is 80 mOhms, and the gate charge is typically 13NC with a switching charge of 4.1 NC. High-power, high-current, low-impedance, fully shielded inductors for digital power amplifiers. With a very small resistance value = 0.013 ohms actual measurement, current = 14A. Very little radiation and interference, very large currents, and higher frequency operating parameters. Minimize digital power amplifier distortion.
