The maximum power supply voltage for the LM324KAPW is ±18V or 36V total supply voltage.
No, the LM324KAPW is a general-purpose op-amp and is not suitable for high-frequency applications. It has a bandwidth of 1 MHz, which is relatively low.
Yes, the LM324KAPW can be used in a single-supply configuration. However, the input common-mode voltage range is limited, and the output voltage swing is reduced when operating from a single supply.
The input impedance of the LM324KAPW is typically around 2 MΩ, but it can vary depending on the specific application and operating conditions.
The LM324KAPW can be used in audio applications, but it may not be the best choice due to its relatively high noise floor and limited bandwidth. A dedicated audio op-amp like the LM833 or OPA2134 may be a better option.
