TM e® EPAD D E L B A N E ALD1721/ALD1721G PRECISION MICROPOWER CMOS OPERATIONAL AMPLIFIER GENERAL DESCRIPTION The ALD1721/ALD1721G is a monolithic CMOS micropower high slew rate operational amplifier intended for a broad range of precision applications requiring exremely low input signal power.
Input signal power is the product of input offset voltage and input bias current, which represents the minimum required power draw from the signal source in order to drive the input of the operational amplifier.
Input signal power is also a figure of merit in source loading and its associated error, and is a measure of the basic signal resolution possible through the operational amplifier for a given signal source.
For certain types of signal sources, signal loading directly translates into a significant distortion or "interface noise equivalent" term.
The ALD1721/ALD1721G is designed to set a new standard in low input signal power requirements.
The typical input loading at its input is 0.
05 mV offset voltage and 0.
01 pA input bias current at 25C, resulting in 0.
0005 fW input signal power draw.
This input characteristic virtually eliminates any loading effects on most types of signal sources, offering unparalled accuracy and signal integrity and fidelity.
Obviously, for capacitive and high sensitivity, high impedance signal sources, the ALD1721/ ALD1721G is ideally suited.
It is readily suited for +5V single supply (or ±1V to ±5V) systems, with low operating power dissipation, a traditional strength of CMOS technology.
It is offered with industry standard pin configuration of µA741 and ICL7611 types.
The ALD1721/ALD1721G can operate with rail to rail large signal input and output voltages with relatively high slew rate.
The input voltage can be equal to or exceed the positive and negative supply voltages while the output voltage can swing close to these supply voltage rails.
This feature significantly reduces the supply overhead voltage requir...
