翻两番运算放大器 QUADRUPLE OPERATIONAL AMPLIFIERS
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
