Ty the unused inputs to ground with a 10K resistor, float the unused outputs.
Bill -----Original Message----- From: neonixie-l@googlegroups.com [mailto:neonixie-l@googlegroups.com] On Behalf Of chuckrr Sent: Thursday, April 01, 2021 8:53 AM To: neonixie-l@googlegroups.com Subject: [neonixie-l] LM-324 op amp What is standard procedure for tying off unused op-amp inputs? If for instance there is a circuit which uses only (2) of the (4) available op-amps in a DIP package, what is the normal protocol for dealing with these unused units? Can the unused inputs just be left floating? Doing do on an LM-324 runs the output at around 7.45 volts when the chip is operating from a single 9 volt supply. Does doing this draw more current than tying off inputs to GND? Thanks, Chuck -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
