ALD1721PAL

The ALD1721/ALD1721G is a monolithic CMOS micropower high slew rate operational amplifier with extremely low input signal power requirements. It is ideal for a broad range of precision applications requiring accurate signal reproduction.

The ALD1721/ALD1721G has a typical input loading of 0.05 mV offset voltage and 0.01 pA input bias current at 25C, resulting in 0.0005 fW input signal power draw. This virtually eliminates any loading effects on most types of signal sources, offering unmatched accuracy and signal integrity.

The ALD1721/ALD1721G can operate with rail-to-rail large signal input and output voltages with relatively high slew rate. It can also accommodate mixed applications where digital and analog circuits may operate off the same power supply or battery.

The ALD1721/ALD1721G is available in a variety of packages, including SOIC, PDIP, and CERDIP. It is also available in a commercial grade (-40°C to 85°C) or industrial grade (-55°C to 125°C) temperature range.
