ALD2702B

The ALD2702 is a dual monolithic operational amplifier intended primarily for a wide range of analog applications in +5V single power supply and ±5V dual power supply systems as well as +4V to +12V battery operated systems. All ALD2702 characteristics are specified for +5V single supply or ±2.5V dual supply systems. The device has an input stage that operates to +300mV above and -300mV below the supply voltages with no adverse effects and/or phase reversals. It offers popular industry pin configuration.

The ALD2702 has been developed specifically with the +5V single supply or ±2.5V dual supply user in mind. 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. Secondly, the device was designed to accommodate mixed applications where digital and analog circuits may work off the same 5V power supply. Thirdly, the output stage can drive up to 400pF capacitive and 5K 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, a slew rate of 1.9V/ms, low power dissipation, low offset voltage and temperature drift, make the ALD2702 a truly versatile, user friendly, operational amplifier.

The ALD2702 is designed and fabricated with silicon gate CMOS technology, and offers less than 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 7mV/ which eliminates many trim or temperature compensation circuits. For precision applications, the ALD2702 is designed to settle to 0.01% in 8ms.
