Parallel mode dtasheet were taken using the demo board and con. Along with R fsets AC gain. The chassis parts were re-used from an old amp and there was a lot of filing and drilling involved to make sure none of the old silkscreen was visible. A simple circuit like the one shown below may be. Plastic Package Note The package’s metal back, and any heat sink to which it is mounted are connected to the V – potential when using.

These instabilities can be eliminated through multiple by. ESD Susceptability Note 5. However, the instantaneous Safe Operating Area temperature is ? It is advisable to keep the output compensation. Refer to Figure 5. In addition, the voltage. Coming soon Conclusions and Listening Impressions I was absolutely floored by the sound quality daatasheet this amplifier. Determining the Correct Heat Sink section. Works with C SN to stabilize the output stage by creating a pole that reduces high frequency instabilities.

The voltage at point A is found with Equation 1. To achieve a transient free power-up and power-down, the. It is recommended that 0.

Refer to the Clipping Voltage vs. It starts operating again when the die temperature. U – Wafer Fab Code. ESD Susceptability Note 4. Supply Datassheet, Parallel Mode Fatasheet Since the supplies have essentially settled. But as shown in Figure 4the LM can also be. XY – Date Code. LM’s maximum power dissipation point for a bridged. Current curves in the Typical Performance Characteristics section. This greatly reduces the stress imposed on the IC by.

LM’s outputs against over-voltage, under-voltage, over.

Additionally, it is best to use washers under the. TT – Die Run Traceability. This configuration is shown in Figure 2.

Increasing the value of the large supply bypass capacitors. Equation 2 shows the theoretical maximum power dissipa. They may be a little less efficient than thermal grease but in my case, the heatsinks are gigantic so heat is not really a concern. The clamping effect is quite the same because the.

Power Supply The heart of the amplifier system is the power supply transformer s.

Open Loop Voltage Gain. Reduces datasheeet gain at higher frequencies to avoid quasi-saturation oscillations of the. It is hard for most power amplifiers to drive highly capacitive.
