LM392/LM2924

Low Power Operational Amplifier/Voltage Comparator

n Power drain suitable for battery operation

n Pin-out is the same as both the LM358 dual op amp and

the LM393 dual comparator

General Description

The LM392 series consists of 2 independent building block

circuits. One is a high gain, internally frequency compen-

sated operational amplifier, and the other is a precision volt-

age comparator. Both the operational amplifier and the volt-

age comparator have been specifically designed to operate

from a single power supply over a wide range of voltages.

Both circuits have input stages which will common-mode in-

put down to ground when operating from a single power sup-

ply. Operation from split power supplies is also possible and

the low power supply current is independent of the magni-

tude of the supply voltage.

Features

n Wide power supply voltage range

Single supply: 3V to 32V

1.5V to 16V

Dual supply:

n Low supply current drain — essentially independent of

supply voltage: 600 µA

n Low input biasing current: 50 nA

n Low input offset voltage: 2 mV

n Low input offset current: 5 nA

n Input common-mode voltage range includes ground

n Differential input voltage range equal to the power

supply voltage

Application areas include transducer amplifier with pulse

shaper, DC gain block with level detector, VCO, as well as all

conventional operational amplifier or voltage comparator cir-

cuits. Both circuits can be operated directly from the stan-

dard 5 V_DCpower supply voltage used in digital systems,

and the output of the comparator will interface directly with

either TTL or CMOS logic. In addition, the low power drain

makes the LM392 extremely useful in the design of portable

equipment.

ADDITIONAL OP AMP FEATURES

n Internally frequency compensated for unity gain

n Large DC voltage gain: 100 dB

n Wide bandwidth (unity gain): 1 MHz

n Large output voltage swing: 0V to V⁺− 1.5V

Advantages

n Eliminates need for dual power supplies

n An internally compensated op amp and a precision

comparator in the same package

ADDITIONAL COMPARATOR FEATURES

n Low output saturation voltage: 250 mV at 4 mA

n Output voltage compatible with all types of logic systems

n Allows sensing at or near ground
