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.

AC Test Circuit

Figure 2 shows a typical test circuit for evaluation of the

LM2405. This circuit is designed to allow testing of the

LM2405 in a 50

Ω environment, such as a pulse generator,

oscilloscope or network analyzer. The 4950

Ω resistor at the

output forms a 100:1 voltage divider when connected to a

50

Ω load.

DS012682-3

Note: 8 pF is total load plus parasitic capacitance.

Note: Adjust Vtest for +2.6V DC at LM2405 input pins. See “Input Resistance” section of Application Hints.
