All device characteristics are specified for +5V single supply or ±2.5V dual supply systems. Supply current is 500µA maximum at 5V supply voltage. It is manufactured with Advanced Linear Devices' enhanced ACMOS silicon gate CMOS process. The ALD2701A/ALD2701B/ALD2701 is designed to offer a trade-off of performance parameters providing a wide range of desired specifications. 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 ICL7621 types. Several important characteristics of the device make application easier to implement at those voltages. First, each 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. This feature allows numerous analog serial stages and flexibility in input signal bias levels. Second, each device was designed to accommodate mixed applications where digital and analog circuits may operate off the same power supply or battery. Third, the output stage can typically drive up to 50pF capacitive and 10KΩ resistive loads. These features, combined with extremely low input currents, high open loop voltage gain of 100V/mV, useful bandwidth of 700KHz, a slew rate of 0.7V/µs, low power dissipation of 0.5mW, low offset voltage and temperature drift, make the ALD2701A/ALD2701B/ALD2701 a versatile, micropower dual operational amplifier. The ALD2701A/ALD2701B/ALD2701, designed and fabricated with silicon gate CMOS technology, offers 1pA typical input bias current. On chip offset voltage trimming allows the device to be used without nulling in most applications. Due to low voltage and low power operation, reliability and operating characteristics, such as input bias currents and warm up time, are greatly improved. Additionally, robust design and rigorous screening make this device especially suitable for operation in temperature-extreme environments and rugged conditions.
