The LM158J is a two independent, high gain, internally frequency compensated Operational Amplifier which was 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. Application areas include transducer amplifiers, DC gain blocks and all the conventional op-amp circuits which now can be more easily implemented in single power supply systems. For example, the LM158 series can be directly operated off of the standard 3.3V power supply voltage which is used in digital systems and will easily provide the required interface electronics without requiring the additional ±15V power supplies.
● Internally frequency compensated for unity gain
● Very low supply current drain (500µA) - Essentially independent of supply voltage
● Input common-mode voltage range includes ground
● Differential input voltage range equal to the power supply voltage
● Large output voltage swing
● Eliminates need for dual supplies
● Compatible with all forms of logic
● Power drain suitable for battery operation
● 100dB Large DC voltage gain
● 2mV Low input offset voltage
●Device has limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
