The recommended operating temperature range for the NE542N is 0°C to 70°C, although it can function up to 85°C with reduced performance.
To ensure stability, use a compensation capacitor (e.g., 10-100 pF) between the output and the inverting input, and consider adding a resistor (e.g., 1 kΩ) in series with the capacitor to prevent oscillations.
The maximum power dissipation for the NE542N is 500 mW per amplifier, assuming a 50°C/W junction-to-ambient thermal resistance.
Yes, the NE542N can be used as a single-ended amplifier by connecting the non-inverting input to a reference voltage and the inverting input to the signal source.
To minimize noise, use a low-impedance power supply, decouple the power supply lines with capacitors, and keep the amplifier inputs and outputs away from noisy signals and high-current paths.
