LM324 General Purpose Audio Operational Amplifier (OpAmp)

Notes;

	Although intended for operation from a supply voltage V_S = +30 Volts (i.e. V_S = ± 15 V or V_CC = +15 V, V_EE = -15 V), the LM324 can operate down to V_S = +3 Volts.
	Input Common Mode Voltage Range V_ICR extends from ground to supply V_CC - 1.5 V i.e. by 0V < V_ICR < V_CC - 1.5V)
	Output Voltage Range V_O extends from ground (+5 mV) to supply V_CC - 2.0V at I_O = 1.5 mA V (i.e. 0.02V < V_O < V_CC - 2.0V)
	Input noise voltage e_n = 35 nV which is adequately low for general purpose communications audio (much better than LM348!).
