Advanced Linear Devices ALD4704A

The ALD4704A/ALD4704B/ALD4704 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. The output voltage swings to within 60mV of either positive or negative power supply voltages at rated load.

GENERAL DESCRIPTION

Typically the input voltage can be beyond positive power supply voltage V+ or the negative power supply voltage V- by up to 300mV. With high impedance load, the output voltage of the ALD4704A/ ALD4704B/ALD4704 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 ALD4704A/ALD4704B/ALD4704 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 ALD4704A/ALD4704B/ ALD4704 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 5.
