GENERAL DESCRIPTION
The AS2111 dual voltage comparator is two AS111
type comparators in a single hermetic package.
CONNECTION DIAGRAM
Featuring all the same performance characteristics of the
single, these duals offer in addition closer thermal
tracking, lower weight, reduced insertion cost and smaller
size than two singles. For additional information, see
the AS111 data sheet.
The AS2111 is specified for operation over the
-55°C to +125°C military temperature range.

NOTES:
1. This rating applies for ±15V supplies. The positive input voltage limit is 30V above the negative supply. The negative input voltage limit is equal
to the negative supply voltage or 30V below the positive supply, whichever is less.
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 resistance 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/V, junction to ambient.
3. These specifications apply for V
S
= ±15V and -55°C < T
A
< 125°C, unless otherwise stated. The offset voltage, offset current and bias current
specifications apply for any supply voltage from a single 5V supply up to ±15V supplies.
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 1mA load.
Thus, these parameters define an error band and take into account the worst case effects of voltage gain and input impedance.
5. The response time specified is for a 100mV input step with 5mV overdrive.
