Note 1: Absolute Maximum Ratings indicate 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
the test conditions, see the Electrical Characteristics. Datasheet min/max specification limits are guaranteed by design, test, or statistical analysis. 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: Linearity Error is the variation in dc gain from VIN= 1.5 volts to VIN = 4.5 volts.
Note 5: Measured with 1in2 copper on PCB connected to pins 3, 4, 5, 10, 11, 12. See Thermal Considerations Section.
Test Circuit
Figure 2 shows the test circuit for evaluation of the LM2481 Clamp Amplifier. A high impedance Voltmeter (>100M
Ω) is used for
DC measurements at the output.
