Product details
Frequently asked questions
What is the equivalent for AD8684ARZ?
The ADA4062-4ARUZ is a JFET quad op-amp in a similar 14-SOIC package, but with a 1.4 MHz GBW and 3.3 V/µs slew rate — slower than the AD8684ARZ. The AD8625ARZ-REEL7 offers 5 MHz GBW and rail-to-rail output but operates on a 5 V supply. Neither is a direct pin-compatible replacement; check your supply voltage and bandwidth needs before substituting.
Is AD8684ARZ rail-to-rail output?
No, the AD8684ARZ does not have rail-to-rail output. Its output swing is limited by the supply rails; for rail-to-rail operation, consider the AD8625ARZ-REEL7.
What is the pinout of AD8684ARZ?
The AD8684ARZ uses the standard 14-SOIC quad op-amp pinout: pin 1 is output A, pin 2 is inverting input A, pin 3 is non-inverting input A, pin 4 is V+, pin 5 is non-inverting input B, pin 6 is inverting input B, pin 7 is output B, pin 8 is output C, pin 9 is inverting input C, pin 10 is non-inverting input C, pin 11 is V-, pin 12 is non-inverting input D, pin 13 is inverting input D, pin 14 is output D.
