Full range for the µA741C is 0°C to 70°C and the µA741M is –55°C to 125°C. This typical value applies only at frequencies above a few hundred hertz because of the effects of drift and thermal feedback. 110 VO = ±10 V RL = 2 kΩ TA = 25°C 200 VCC+ = 15 V VCC – = –15 V VO = ±10 V RL = 2 kΩ TA = 25°C 100 AVD – Open-Loop Signal Differential Voltage Amplification – dB Graphe extra AVD – Open-Loop Signal Differential Voltage Amplification – V/mV 400 100 40 20 90 80 70 60 50 40 30 20 10 0 10 0 2 4 6 8 10 12 14 16 VCC ± – Supply Voltage – V 18 20 Figure 6.
