FEATURES
DESCRIPTION
The lm392-N series consists of 2 independent
2
• Wide Power Supply Voltage Range
building block circuits. One is a high gain, internally
– Single Supply: 3V to 32V
frequency compensated operational amplifier, and the
– Dual Supply: ±1.5V to ±16V
other is a precision voltage comparator. Both the
operational amplifier and the voltage comparator
• Low Supply Current Drain—Essentially
have been specifically designed to operate from a
Independent of Supply Voltage: 600 μA
single power supply over a wide range of voltages.
• Low Input Biasing Current: 50 nA
Both circuits have input stages which will common-
• Low Input Offset Voltage: 2 mV
mode input down to ground when operating from a
single power supply. Operation from split power
• Low Input Offset Current: 5 nA
supplies is also possible and the low power supply
• Input Common-Mode Voltage Range Includes

voltage.
• Differential Input Voltage Range Equal to the
Application areas include transducer amplifier with

pulse shaper, DC gain block with level detector, VCO,
• ADDITIONAL OP AMP FEATURES
as well as all conventional operational amplifier or
voltage comparator circuits. Both circuits can be

– Large DC Voltage Gain: 100 dB
of the comparator will interface directly with either
– Wide Bandwidth (Unity Gain): 1 MHz
TTL or CMOS logic. In addition, the low power drain
makes the lm392-N extremely useful in the design of
– Large Output Voltage Swing: 0V to V

portable equipment.
1.5V
• ADDITIONAL COMPARATOR FEATURES
– Low Output Saturation Voltage: 250 mV at 4
mA
– Output Voltage Compatible with all Types
of Logic Systems
ADVANTAGES
• Eliminates Need for Dual Power Supplies
• An Internally Compensated Op Amp and a
Precision Comparator in the Same Package
• Allows Sensing at or Near Ground
• Power Drain Suitable for Battery Operation
• Pin-Out is the Same as Both the LM358 Dual
Op Amp and the LM393 Dual Comparator
