UA747CN . Operational Amplifier, 2 Amplifier, 1 MHz, 0.5 V/µs, ± 9V to ± 15V. The UA747CN is a Dual General-purpose Operational Amplifier features offset-voltage null capability. Each half is electrically similar to UA741. The high common-mode input voltage range and the absence of latch-up make this amplifier ideal for voltage-follower applications. The device is short-circuit protected and the internal frequency compensation ensures stability without external components. A low-value potentiometer may be connected between the offset null inputs to null out the offset voltage. The UA747C is characterized for operation from 0 to 70°C.
