VOLTAGE COMPARATORS
FAIRCHILD LINEAR INTEGRATED CIRCUITS
GENERAL DESCRIPTION - the "A111 and "A311 are monolithic, low input current Voltage Com-
parators, each constructed using the Fairchild Planar· epitaxial process. The "A111 series operates
from the single 5 V integrated circuit logic supplvto the standard ±15 V operational amplifier supplies.
The "A111 series is intended for a wide range of applicatons including driving lamps or relavs and
switching voltages up to 50 V at currents as high as 50 mAo The output stage is compatible with RTl,
OTL, TTL and MOS logic. The input stage current can be raised to increase input slew rate.
• lOW INPUT BIAS CURRENT - 150 nA MAX (111),250 nA MAX (311)
• LOW INPUT OFFSET CURRENT - 20 nA MAX (111),50 nA MAX (311)
• DIFFERENTIAL INPUT VOLTAGE - ±30 V
• POWER SUPPLY VOLTAGE SINGLE 5.0 V SUPPLY TO ±15 V
• OFFSET VOLTAGE NULL CAPABILITY
• STROBE CAPABILITY

NOTES:
1. This rating applies for ± 15 V supplies. The positive input voltage limit is 30 V above the negative supply. The negative input voltage limit is
equal to the negative supply voltage or 30 V below the positive supply, whichever is less.
2. Rating applies to ambient temperatures up to 70°C. Above 70°C ambient derate linearly at 6.3 mW/oC for metal can; 8.3 mW/oC for
mini DIP.
3. The offset voltage, offset current and bias current specifications apply for any supply voltage from a single 5 V supply up to ±15 V 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
1 mA 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 (see definitions) is for a 100 mV input step with 5 mV overdrive.
