Differential voltages are the non-inverting input terminal with respect to the inverting input terminal. 3. The magnitude of input and output voltages must never exceed VCC+ +0.3V. 4. Charged device model: all pins and the package are charged together to the specified voltage and then discharged directly to the ground through only one pin. This is done for all pins. 5. Human body model: A 100pF capacitor is charged to the specified voltage, then discharged through a 1.5kΩ resistor between two pins of the device. This is done for all couples of connected pin combinations while the other pins are floating. 6. Machine model: A 200pF capacitor is charged to the specified voltage, then discharged directly between two pins of the device with no external series resistor (internal resistor < 5Ω). This is done for all couples of connected pin combinations while the other pins are floating Table 2.

From the most important to the least important point: ● Each power supply lead must be bypassed to ground with a 10nF ceramic capacitor very close to the device and a 10μF capacitor. ● To provide low inductance and low resistance common return, use a ground plane or common point return for power and signal. ● All leads must be wide and as short as possible especially for op-amp inputs. This is in order to decrease parasitic capacitance and inductance. ● Use small resistor values to decrease the time constant with parasitic capacitance. ● Choose component sizes as small as possible (SMD). On output, decrease capacitor load to avoid degradation in circuit stability which may cause oscillation. You can also add a serial resistor in order to minimize its influence. 8/13 TSH93 5 Macromodel Macromodel Please consider the following remarks before using this macromodel. ● All models are a trade-off between accuracy and complexity (i.e. simulation time). ● Macromodels are not a substitute to breadboarding; rather, they confirm the validity of a design approach and help to select surrounding component values. ● A macromodel emulates the nominal performance of a typical device within specified operating conditions (temperature, supply voltage, for example). Thus the macromodel is often not as exhaustive as the datasheet, its purpose is to illustrate the main parameters of the product. Data derived from macromodels used outside of the specified conditions (VCC, temperature, for example) or even worse, outside of the device operating conditions (VCC, Vicm, for example), is not reliable in any way.
