my customer is using LM324 in Wireless charger. Now they meet issue about the output range. They are asking about the LM324 maximum output voltage when supply is only single 4.3V. Please help! Thanks!
You can find the information on the output voltage range of the LM324 in the datasheet, section 6.5 - VOH High-level output voltage. The spec given is Vcc-1.5, which means that for a 4.3V supply, the maximum output voltage will be 2.8V. You also have to look at how much current is being sunk from the output as well by looking at figure 1. If there is a large amount of current sinking from the output, the voltage swing will be limited as well.
