GENERAL DESCRIPTION The ALD1712 is a monolithic precision 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 +6V to 12V battery operated systems. 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 and is available as a standard cell in ALD's ASIC "Function-Specific" library. 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. The ALD1712 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 1K Ω resistive loads in non-inverting unity gain connection, and up to 4000pF at a gain of 5. 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 ALD1712 a truly versatile, user friendly, operational amplifier. 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 5 µV/ °C which eliminates many trim or temperature compensation circuits. For precision applications, the 1712 is designed to settle to 0.01% in 8 µs. The unique characteristics at input and output are modeled in an available macromodel.
