The maximum power dissipation of the LM675T is dependent on the thermal resistance of the package and the ambient temperature. According to the datasheet, the maximum power dissipation is 15W when the device is mounted on a 2 oz copper clad board with a thermal resistance of 30°C/W.
To ensure stability in the LM675T, it is recommended to use a minimum output capacitance of 100nF and a minimum ESR of 1 ohm. Additionally, the datasheet recommends using a compensation capacitor of 10nF to 100nF between the output and the inverting input.
The maximum input voltage of the LM675T is ±18V. Exceeding this voltage may cause damage to the device.
Yes, the LM675T can be used as an audio amplifier. It has a high slew rate and bandwidth, making it suitable for audio applications. However, it is recommended to use a low-pass filter to remove high-frequency noise and ensure a clean audio signal.
The LM675T has an internal current limit of 3.5A. To protect the device from overcurrent, it is recommended to use an external current sense resistor and a current limit circuit. Additionally, the datasheet recommends using a fuse or a PTC thermistor to protect the device from excessive current.
