Op Amp Swing Rail-To-Rail Circuit Diagram with Lm324

This is a simple Op Amp Swing Rail-To-Rail Circuit Diagram with Lm324. The LM324 series are low−cost, quad operational amplifiers with true differential inputs. Must Usually Share Noisy Digital Supply. Rail-to-Rail Input and Output Needed to Increase Signal. Swing. Precision Less than the best Dual Supply Op Amps. By using two CMOS inverters, the output for an LM324 op amp can be increased from 3.5 Vpp to 4.9 Vpp. This circuit is only recommended for light loads (<30 mA) and for relatively slow op amps. Any CMOS inverter (74COO, 74C02, 74C14, CD4001, CD4011, etc.) can be used.
