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 krad(Si)
●— ELDRS Free 100 krad(Si)
●■ 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 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
