Internally frequency compensated for unity gain Large DC voltage gain 100 dB Wide bandwidth (unity gain) 1 MHz (temperature compensated) Power Supply Range: Single supply to 32V Very low supply current drain (700 �A)--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 powersupply voltage Large output voltage swing - 1.5V The GM324 series are low�cost, quad internally frequency compesated operational amplifiers with true differential inputs, which operate from a single power supply over a wide range of voltages. They have several distinct advantages over standard operational amplifier types in single supply applications. The quad amplifier can operate at supply voltages as low or as high as 32V with extremely low quiescent current (on a per amplifier basis). The common mode input range includes the negative supply, thereby eliminating the necessity for external biasing components in many applications. The output voltage range also includes the negative 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 GM324 series can be directly operated off of the standard +5V power supply voltage which is used in digital systems and will easily provide the required interface electronics without requiring the additional �15V power supplies. The GM324 is available in DIP-14 and SOP-14 packages.
