FET INPUT VOLTAGE COMPARATORS
FAIRCHILD LINEAR INTEGRATED CIRCUITS
GENERAL DESCRIPTION - The IlAF111 and IlAF311 are monolithic, FET input Voltage Compare-
tors, constructed using the Fairchild Planar* epitaxial process. The ,uAF111 series operates from the
single 5 V integraetd circuit logic supply to the standard ±15 V operational amplifier supplies. The
.uAF111 series is intended for a wide range of applications including driving lamps or relays and
switching voltages up to 50 Vat currents as high as 50 mAo The output stage is compatible with RTL,
DTL, TTL and MOS logic. The input stage current can be raised to increase input slew rate.

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 10°C. Above 70°C ambient derate linearly at 6.3 mW/oC for metal can; 8.3 mW/oC for 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 in·to 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.
6. For input voltages greater than 15 V above the negative supply the bias and offset currents will increase - see typical performance curves.
