GM358 LOW POWER DUAL OPERATIONAL AMPLIFERS Description Features The GM358 consists of two high gain, internally frequency compensated operational amplifiers which are designed to operated from a single power supply over a wide range of voltages. Operation from split power supplies is also available. The GM358 feature low power drain, a common mode input voltage range extending to GND/VEE. The GM358 is equivalent to one-half of the GM324. True Differential Input Stage Internally Frequency Compensated for Unity Gain Single Supple Operation: 3V to 40V Wide Bandwidth (unity Gain, temperature compensated): 1 MHz Short Circuit Protected Outputs 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 GM358 can be directly operated 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. Low Input Bias Current Common Mode Range Extends to Negative Supply Single and Split Supply Operation The GM358 is available in SOP-8 and DIP-8 packages.
