The maximum power supply voltage for the NE536T is ±18V. Exceeding this voltage can cause damage to the device.
To ensure stability in a unity-gain configuration, add a 10-100nF capacitor between the output and the inverting input to prevent oscillations.
The recommended operating temperature range for the NE536T is -25°C to +85°C. Operating outside this range can affect the device's performance and reliability.
While the NE536T can be used as a comparator, it's not recommended due to its relatively slow slew rate (0.5V/μs) and limited output current (±10mA). A dedicated comparator IC would be a better choice for most applications.
To minimize noise and hum, use proper grounding and shielding techniques, keep the input and output traces short and away from each other, and consider adding a 10-100nF capacitor between the power supply pins to filter out noise.
