ROHM TLR377YG-C Non Inverting Amplifier Frequency Response Simulation

ROHM-TLR377YG-C-Non-Inverting-Amplifier-Frequency-Response-Simulation-
PRODACT-IMG

This circuit simulates the frequency response with Op-Amp as a non-inverting amplifier. You can observe the AC gain and phase of the ratio of output to input voltage when the input source voltage AC frequency is changed. 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 variances 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 recommend to double check those characteristics with actual board where the chips will be mounted on.

Simulation Schematic

FIG-1

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.

Op-Amp model

Table 3 shows the model pin function implemented. Note that the Op-Amp model is the behavior model for its input/output characteristics, and no protection circuits or the functions not related to the purpose are not implemented.

The default value of ESR is 0.01 Ω.
(Note 2) These parameters can take any positive value or zero in simulation but it does not guarantee the operation of the IC in any condition. Refer to the datasheet to determine adequate value of parameters.
