Overview
The AD8004SQ, produced by Analog Devices Inc., is a quad, low power, high speed operational amplifier. It is designed to operate on single or dual supplies and utilizes a current feedback architecture. This amplifier is notable for its high slew rate of 3000 V/μs, making it ideal for handling large amplitude pulses. The AD8004SQ is fully specified for a +5 V supply and can operate within a power supply range of +4 V to +12 V. It is particularly suited for applications where high speed, low power consumption, and compact packaging are critical.
