低功耗四路运算放大器 14-CFP -55 to 125

General Description

The LM124/124A consists of four independent, high gain, in ternally frequency compensated operational amplifiers which

were designed specifically 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.

Features

■ Available with Radiation Guarantee

— High Dose Rate 100 kradSi

— ELDRS Free 100 kradSi

■ Internally frequency compensated for unity gain

■ Large DC voltage gain  100 dB

■ Wide bandwidth unity gain  1 MHztemperature compensated

■ Wide power supply range:  Single supply  3V to 32V  or dual supplies  ±1.5V to ±16V

■ Very low supply current drain 700 μA—essentially independent of supply voltage

■ Low input biasing current  45 nA temperature compensated

■ Low input offset voltage  2 mV and offset current:  5 nA

■ Input common-mode voltage range includes ground

■ Differential input voltage range equal to the power supply voltage

■ Large output voltage swing  0V to V+ − 1.5V

Advantages

■ Eliminates need for dual supplies

■ Four internally compensated op amps in a single package

■ Allows directly sensing near GND and VOUT also goes to GND

■ Compatible with all forms of logic

■ Power drain suitable for battery operation
