ALD1722GDA Image

The ALD1722GDA from Advanced Linear Devices is a Low-Power CMOS Operational Amplifier that has been designed for a broad range of precision applications requiring a very low input signal power to drive the amplifier. It requires a supply voltage of ±2 V to ±5 V, and an input offset and bias current of 0.01 pA. This op-amp provides an output voltage of 4.998 V, a large signal voltage gain of 250 V/mV, and a common-mode rejection ratio (CMRR) of 97 dB. It offers excellent input characteristics to virtually eliminate any loading effects on most types of signal sources, offering unparalleled accuracy, signal integrity, and signal fidelity. This amplifier can be used in single +5 V supply systems with low operating power dissipation and is designed using CMOS technology. It can operate with rail-to-rail large signal input and output voltage levels with a relatively high slew rate.

This op-amp is user-friendly and easy to use with virtually no source loading and zero input-loading-induced source errors. It has undergone robust design and rigorous screening test procedures, making this device especially suitable for operating in temperature-extreme environments and rugged conditions. This operational amplifier is available in a surface-mount package that measures 5 x 4.05 x 1.75 mm and is ideal for system output level shifters, precision sample and hold amplifiers, precision current-to-voltage converters, precision gain amplifiers, transducer biasing circuits, precision cable drivers, sensor interface circuits, biochemical, and portable applications.
