Low Noise High Output Drive Rail-to-Rail input/output CMOS Operational
Amplifier TLR2374FV-LB – Non-inverting Amplifier (Sine Wave Input) – Transient
Response simulation
This circuit simulates the transient response to sine wave input with a non-
inverting amplifier configured Op-Amps. You can observe the output voltage and
how faithfully the sine wave input voltage is reproduced. You can customize
the parameters of the components shown in blue, such as VSOURCE, or peripheral
components, and simulate the non-inverting amplifier with the desired
operating condition.
You can simulate the circuit in the published application note: Operational
amplifier, Comparator (Tutorial). [JP] [EN] [CN] [KR]
General Cautions
- Caution 1: The values from the simulation results are not guaranteed. Please use these results as a guide for your design.
- Caution 2: These model characteristics are specifically at Ta=25°C. Thus, the simulation result with temperature variance may significantly differ from the result with the one done at actual application board (actual measurement).
- Caution 3: Please refer to the Application note of Op-Amps for details of the technical information.
- Caution 4: The characteristics may change depending on the actual board design and ROHM strongly recommends to double check those characteristics with actual board where the chips will be mounted on.
Simulation Schematic
How to simulate
The simulation settings, such as parameter sweep or convergence options, are configurable from the ‘Simulation Settings’ shown in Figure 2, and Table 1 shows the default setup of the simulation. In case of simulation convergence issue, you can change advanced options to solve. The temperature is set to 27 °C in the default statement in ‘Manual Options’. You can modify it.
