DESCRIPTION
The ALD2704 is a dual monolithic operational amplifier with MOSFET input that has rail-to-rail input and output voltage ranges. The input voltage range and output voltage range are very close to the positive and negative power supply voltages. Typically the input voltage can be beyond positive power supply voltage V + or the negative power supply voltage V- by up to 300m V. The output voltage swings to within 60m V of either positive or negative power supply voltages at rated load. With high impedance load, the output voltage of the ALD2704 approaches within 1m V of the power supply rails. This device is designed as an alternative to the popular J-FET input operational amplifier in applications where lower operating voltages, such as 9V battery or ± 3.25V to ±6V power supplies are being used. The ALD2704 offers high slew rate of 5V/µs. It is designed and manufactured with Advanced Linear Devices' standard enhanced ACMOS silicon gate CMOS process, and it offers low unit cost and exceptional reliability. The rail-to-rail input and output feature of the ALD2704 expands signal voltage range for a given operating supply voltage and allows numerous analog serial stages to be implemented without losing operating voltage margin. The output stage is designed to drive up to 10m A into 400p F capacitive and 1.5K Ω resistive loads at unity gain and up to 4000p F at a gain of 5. Short circuit protection to either ground or the power supply rails is at approximately 15m A clamp current. Due to plementary output stage design, the output can source and sink 10m A into a load with symmetrical drive and is ideally suited for applications where push-pull voltage drive is desired. For each of the operational amplifier, the offset voltage is trimmed on-chip to eliminate the need for external nulling in many applications. For precision applications, the output is designed to settle to 0.1% in 2 µs. In large signal buffer applications, the operational amplifier can function as an...
