1. All voltage values, except differential voltage are with respect to network ground terminal. 2. 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 1.5k 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 < 5). This is done for all couples of connected pin combinations while the other pins are floating

Printed circuit layout
As for any high frequency device, a few rules must be observed when designing the PCB to get the best performance from this high speed op-amp. 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 10F 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.

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. This macromodel applies to: TSH93I ** Standard Linear Ics Macromodels, 1997. ** CONNECTIONS : * 1 INVERTING INPUT * 2 NON-INVERTING INPUT * 3 OUTPUT * 4 POSITIVEPOWER SUPPLY * 5 NEGATIVE POWER SUPPLY .SUBCKT TSH93 1 3 2 4 5(analog) * * ** * ** * ** * ** * ** * ** * ** * ** * ** * ** * ** .MODEL MDTH D IS=1E-8 KF=1.809064E-15 CJO=10F * INPUT STAGE CIP 2 5 1.0 0 00E-12 CIN 1 5 1.0 0 00E-12 EIP 10 5 2 5 1 EIN 16 5 1 5 1 RIP 10 11 2.60 0 0E-01 RIN 15 16 2.60 0 0E-01 RIS 11 15 3.645298E-01 DIP 11 12 MDTH 400E-12 DIN 15 14 MDTH 400E-12 VOFP 12 13 DC 0.0 0 00E+00 VOFN 13 14 DC 0 IPOL 13 5 1.0 0 00E-03 CPS 11 15 2.986990E-10 DINN 17 13 MDTH 400E-12 VIN 17 5 2.0 0 00e+00 DINR 15 18 MDTH 400E-12 VIP 4 18 1.0 0 00E+00 FCP 4 5 VOFP 3.50 0 0E+00 FCN 5 4 VOFN 3.50 0 0E+00 FIBP 2 5 VOFP 1.0 0 00E-02 FIBN 5 1 VOFN 1.0 0 00E-02 * AMPLIFYING STAGE FIP 5 19 VOFP 2.530000E+02 FIN 5 19 VOFN 2.530000E+02
