Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur.
Note 2: Operating ratings indicate conditions for which the device is functional, but do not guarantee specific performance limits. For guaranteed specifications and
test conditions, see the Electrical Characteristics. The guaranteed specifications apply only for the test conditions listed. Some performance characteristics may
change when the device is not operated under the listed test conditions.
Note 3: All voltages are measured with respect to GND, unless otherwise specified.
Note 4: Calculated value from Voltage Gain test on each channel.
Note 5: Linearity Error is the variation in dc gain from V
Note 6: Input from signal generator: t

AC Test Circuit
Note: 8 pF load includes parasitic capacitance.
Figure 2 shows a typical test circuit for evaluation of the LM2437. This circuit is designed to allow testing of the LM2437 in a 50
environment without the use of an expensive FET probe. The two 2490 resistors form a 200:1 divider with the 50 resistor and
the oscilloscope. A test point is included for easy use of an oscilloscope probe.The compensation capacitor is used to compen-
sate the stray capacitance of the two 2490
