LMx24-N, LM2902-N Low-P ower, Quad-O perational Ampliers

1 Features

1 • Internally Frequency Compensated for Unity Gain

• Large DC Voltage Gain 100 dB

• Wide Bandwidth (Unity Gain) 1 MHz

(Temperature Compensated)

• Wide Power Supply Range:

– Single Supply 3 V to 32 V

– or Dual Supplies ±1.5 V to ±16 V

• Very Low Supply Current Drain (700 A)μ

—Essentially Independent of Supply Voltage

• Low Input Biasing Current 45 nA

(Temperature Compensated)

• Low Input Oset Voltage 2 mV

and Oset Current: 5 nA

• Input Common-Mode Voltage Range I ncludes

Ground

• Dierential I nput Voltage Range Equal to the

Power Supply Voltage

• Large Output Voltage Swing 0 V to V + −1.5 V

• Advantages:

– Eliminates Need for Dual Supplies

– Four Internally Compensated Op Amps in a

Single Package

– Allows Dir ect Sensing Near GND and VOUT

also Goes to GND

– Compatible With All Forms of Logic

– Power Drain Suitable for Battery Operation

– In the Linear Mode the Input Common-Mode,

Voltage Range Includes Ground and the

Output Voltage

– Can Swing to Ground, Even Though Operated

from Only a Single Power Supply Voltage

– Unity Gain Cross Frequency is Temperature

Compensated

– Input Bias Current is Also Temperature

Compensated

2 Applications

• Transducer Ampliers

• DC Gain Blocks

• Conventional Op Amp Circuits

3 Description

The LM124-N series consists of four independent,

high-gain, internally frequency compensated

operational ampliers designed to operate from a

single power supply over a wide range of voltages.

Operation from split-power supplies is also possible

and the low-power supply current drain is

independent of the magnitude of the power supply

voltage.

Application areas incl ude transducer ampliers, DC

gain blocks and all t he conventional op amp circuits

which now c an be more easily implemented in single

power supply systems. For example, the LM124-N

series can directly operate o of the standard 5-V

power s upply voltage which is used in digital systems

and easily provides the required interface electronics

without requiring the additional ±15 V power supplies.
