ALD2724E
Overview
- System level “calibration” capable GENERAL DESCRIPTION The ALD2724E/ALD2724 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 300mV. The output voltage swings to within 60mV of either positive or negative power supply voltages at rated load. With high impedance load, the output voltage of the ALD2724E/ALD2724 approaches within 1mV 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 ± 5V power supplies are being used. The ALD2724E/ALD2724 offers high slew rate of 5.0V/µs. The rail-to-rail input and output feature of the ALD2724E/ALD2724 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 10mA into 400pF capacitive and 1.5KΩ resistive loads at unity gain and up to 4000pF at a gain of
- Short circuit protection to either ground or the power supply rails is at approximately 15mA clamp current. Due to complementary output stage design, the output can source and sink 10mA into a load with symmetrical drive and is ideally suited for applications where push-pull voltage drive is desired.
