■ APPLICATION NOTE Single and Dual Supply Voltage Operation The NJM2740 works with both single supply and dual supply when the voltage supplied is between V+ and V−. These amplifiers operate from single 2.2 to 7V supply and dual ±1.1V to ±3.5V supply. Common-Mode Input Voltage Range When the supply voltage does not meet the condition of electrical characteristics, the range of common-mode input voltage is as follows: VICM (typ.) = V−+1.1V to V+-1V (Ta = 25°C) Difference of VICM when Temperature change, refer to typical characteristic graph. During designing, consider variations in characteristics for use with allowance. Maximum Output Voltage Range When the supply voltage does not meet the condition of electrical characteristics, the range of the typ. value of the maximum output voltage is as follows: VOM (typ.) = V-+0.3V to V+-0.3V (RL=2.5kΩ to V+/2, Ta=25°C) During designing, consider variations in characteristics and temperature characteristics for use with allowance. In addition, also note that the output voltage range becomes narrow as shown in typical characteristics graph when an output current increases. Input Voltage Exceeding the Supply Voltage Inputs of the NJM2740 are protected by ESD diodes (shown in Figure1) that will conduct if the input voltages exceed the power supplies by more than approximately 300mV. Momentary voltages greater than 300mV beyond the power supply, inputs can be tolerated if the current is limited to 1mA. Figure2 is easily accomplished with an input resistor. If the input voltage exceeds the supply voltage, the input current must be limited 1mA or less by using a restriction resistance (RLIMIT) as shown in figure2.

Capacitive load The NJM2740 can use at unity gain follower, but the unity gain follower is the most sensitive configuration to capacitive loading. The combination of capacitive load placed directly on the output of an amplifier along with the output impedance of the amplifier creates a phase lag which in turn reduces the phase margin of the amplifier. If phase margin is significantly reduced, the response will cause overshoot and ringing in the step response. It is 30 degree phase margin at 1000pF capacitive load. To drive heavy capacitive loads, an isolation resistor, RISO as shown Figure3, should be used. RISO improves the feedback loop’s phase margin by making the output load resistive at higher frequencies. The larger the value of RISO, the more stable the output voltage will be. However, larger values of RISO result in reduced output swing, reduced output current drive and reduced frequency bandwidth.
