GENERAL DESCRIPTION

All device characteristics are specified for +5V single supply or ±2.5V dual supply systems. Supply current is 250µA maximum at 5V supply voltage. These devices do not add any significant errors, regardless of what the souce impedance variations may be, thereby improving overall system precision and accuracy. The device is designed to offer the benefits of CMOS technology by providing a wide range of desired specifications. The most important of these specifications is extremely low input bias/offset currents at extremely low input offset voltages. It has been developed specifically for the +5V single supply or ±1V to ±5V dual supply user and offers the popular industry standard pin configuration of µA741 and ICL7611 types. Several additional important characteristics of the device make application easier to implement at those voltages. First, the operational amplifier can operate with rail to rail input and output voltages. This means the signal input voltage and output voltage can be equal to the positive and negative supply voltages.
