All device characteristics are specified for +5V single supply or ±2.5V dual supply systems. It is manufactured with Advanced Linear Devices' enhanced ACMOS silicon gate CMOS process. The ALD1702A/ALD1702B/ALD1702/ALD1703 is designed to offer a balanced trade-off of performance parameters providing a wide range of desired specifications. It has been developed specifically with the 5V single supply or ±2.5 dual supply user in mind and offers the industry pin configuration of µA741 and ICL7611 types. Several important characteristics of the device make many applications easy to implement for these supply voltages. First, the operational amplifier can operate with rail to rail input and output voltages. This feature allows numerous analog serial stages to be implemented without losing operating voltage margin. Second, the device was designed to accommodate mixed applications where digital and analog circuits may work off the same 5V power supply. Third, the output stage can drive up to 400pF capacitive and 5KΩ resistive loads in non-inverting unity gain connection and double the capacitance in the inverting unity gain mode. These features, coupled with extremely low input currents, high voltage gain, useful bandwidth of 1.5MHz, slew rate of 2.1V/µs, low power dissipation, low offset voltage and temperature drift, make the ALD1702A/ ALD1702B/ALD1702/ALD1703 a truly versatile, user friendly, operational amplifier. The ALD1702A/ALD1702B/ALD1702/ALD1703 is designed and fabricated with silicon gate CMOS technology, and offers 1pA typical input bias current. On-chip offset voltage trimming allows the device to be used without nulling in most applications. The device offers typical offset drift of less than 7µV/°C which eliminates many trim or temperature compensation circuits. For precision applications, it is designed to settle to 0.01% in 8µs. Additionally, robust design and rigorous screening make this device especially suitable for operation in temperature-extreme environments and rugged conditions.
