The JRC4580 is a dual op amp chip with an optimal supply voltage range of ±5V to ±18V. In this range, it can provide stable working performance and low distortion. Lower supply voltages can reduce power consumption, but may affect output power and dynamic range. Higher supply voltages can provide greater output power and wider dynamic range, but also increase power consumption and distortion. Therefore, according to the specific application requirements, choosing the appropriate power supply voltage is the key to ensure the normal operation of JRC4580.
Dual op amp JRC4580, this can be replaced with dual op amp, such as: JRC4558, NE5532, LM4562, OPA2604 (voltage can not be lower than 9V or plus or minus 4.5V). It is said that the 4580 is used on the gold noise, which is a low noise dual operational amplifier.
