■Low input bias current: 20nA (temperature compensated)

■Low input offset current: 2nA

■Differential input voltage range equal to the power supply voltage

Large output voltage swing 0V to (V CC+ -1.5V)

Description

This circuit consists of two independent, high gain, internally frequency-compensated

operational amplifiers designed specifically for automotive and industrial control systems. It operates from a single power supply over a wide range of voltages. The low power supply drain is independent of the magnitude of the power supply voltage.

Application areas include transducer amplifiers, DC gain blocks and all the conventional op-amp circuits which now can be more easily

implemented in single power supply systems. For example, these circuits can be directly supplied from the standard +5V which is used in logic systems and will easily provide the required interface electronics without requiring any additional power supply.

In the linear mode, the input common-mode voltage range includes ground and the output voltage can also swing to ground, even though operated from a single power supply.

Input current (4): V in driven negative

Input current (5): V in driven positive above AMR value

4.This input current only exists when the voltage at any of the input leads is driven negative. It is due to the

collector-base junction of the input PNP transistor becoming forward-biased and thereby acting as input diode clamp. In addition to this diode action, there is NPN parasitic action on the IC chip. This transistor action can cause the output voltages of the Op-amps to go to the V CC voltage level (or to ground for a large overdrive) for the time during which an input is driven negative.

This is not destructive and normal output is restored for input voltages above -0.3V.5.The junction base/substrate of the input PNP transistor polarized in reverse must be protected by a resistor

in series with the inputs to limit the input current to 400μA max (R =(Vin-32V)/400μA).5mA in DC or 50mA in AC (duty cycle = 10%, T=1s)

1. V O = 1.4V, R S = 0Ω, 5V < V CC+ < 30V, 0V < V ic < V CC+ - 1.5V.

2.The direction of the input current is out of the IC. This current is essentially constant, independent of the state of the output,

so there is no change in the loading charge on the input lines.3.The input common-mode voltage of either input signal voltage should not be allowed to go negative by more than 0.3V.

The upper end of the common-mode voltage range is V CC+ –1.5V, but either or both inputs can go to +32V without damage.4.Due to the proximity of external components ensure that stray capacitance does not cause coupling between these

external parts. This typically can be detected at higher frequencies because this type of capacitance increases.

4.1

Important note concerning this macromodel

Consider the following remarks before using this macromodel.

●All models are a trade-off between accuracy and complexity (that is, 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 (V CC , temperature, for example) or even worse, outside of the device operating conditions (V CC , V icm , for example), is not reliable in any way.
