Low Offset Voltage

Dual Comparators

The LM393 series are dual independent precision voltage comparators capable of single or split supply operation. These devices are designed to permit a common mode range±to±ground level with single supply operation. Input offset voltage specifications as low as 2.0 mV make this device an excellent selection for many applications in consumer automotive, and industrial electronics.

•Wide Single±Supply Range: 2.0 Vdc to 36 Vdc

•Split±Supply Range: ±1.0 Vdc to ±18 Vdc

•Very Low Current Drain Independent of Supply Voltage: 0.4 mA

•Low Input Bias Current: 25 nA

•Low Input Offset Current: 5.0 nA

•Low Input Offset Voltage: 2.0 mV (max) LM393A

5.0mV (max) LM293/393

•Input Common Mode Range to Ground Level

•Differential Input Voltage Range Equal to Power Supply Voltage

•Output Voltage Compatible with DTL, ECL, TTL, MOS, and CMOS Logic Levels

•ESD Clamps on the Inputs Increase the Ruggedness of the Device without Affecting Performance

NOTES: 1. The maximum output current may be as high as 20 mA, independent of the magnitude of VCC, output short circuits to VCC can cause excessive heating and eventual destruction.

2.At output switch point, VO]1.4 Vdc, RS = 0 Ω with VCC from 5.0 Vdc to 30 Vdc, and over the full input common mode range (0 V to VCC = ±1.5 V).

3.Due to the PNP transistor inputs, bias current will flow out of the inputs. This current is essentially constant, independent of the output state, there fore, no loading changes will exist on the input lines.

4.Input common mode of either input should not be permitted to go more than 0.3 V negative of ground or minus supply. The upper limit of common mode range is VCC ±1.5 V.

5.Response time is specified with a 100 mV step and 5.0 mV of overdrive. With larger magnitudes of overdrive faster response times are obtainable.

6.The comparator will exhibit proper output state if one of the inputs becomes greater than VCC, the other input must remain within the common mode range. The low input state must not be less than ±0.3 V of ground or minus supply.
