parameters define an error band and take into account the worst case effects of voltage gain and input impedance.
Note 5: The response time specified is for a 100 mV input step with 5 mV overdrive.
Note 6: RETS2111X for the LH2111D and LH2111F military specifications.
Electrical Characteristics
Note 1: This rating applies for
tive supply voltage or 30V below the positive supply, whichever is less.
Note 2: The maximum junction temperature is 150˚C. For operating at elevated temperatures, devices in the flat package, the derating is based on a thermal resis-
tance of 185˚C/W when mounted on a 1/16-inch-thick epoxy glass board with 0.03-inch-wide, 2 ounce copper conductor. The thermal resistance of the dual-in-line
package is 100˚C/W, junction to ambient.
Note 3: These specifications apply for V
voltage, offset current and bias current specifications apply for any supply voltage from a single 5V supply up to
Note 4: The offset voltages and offset currents given are the maximum values required to drive the output within a volt of either supply with a 1 mA load. Thus, these
