Overview
The AD8682ARZ-REEL7 is a dual low power, high speed JFET operational amplifier manufactured by Analog Devices Inc. It features a typical gain bandwidth product of 3.5 MHz and a slew rate of 9 V/μs. The device operates within a supply voltage range of ±4.5 V to ±18 V with a maximum supply current of 250 μA per amplifier. Input characteristics include a maximum offset voltage of 1 mV at 25°C and an input bias current of 20 pA at 25°C. The component is housed in an 8-Lead SOIC_N package and supports an operating temperature range from -40°C to +85°C.
Feature Summary
- JFET input stage providing extremely low input bias current
- High slew rate combined with low quiescent supply current
- Unity-gain stable design suitable for driving capacitive loads
- Wide common-mode input voltage range including the positive rail
Applications
- Portable telecommunications equipment
- Low power industrial instrumentation
- Active and precision filters
- Strain gauge amplifiers
- Supply current monitoring circuits
Procurement Notes
Verify the specific ordering suffix REEL7 corresponds to the required tape and reel packaging configuration before procurement. Confirm that the RoHS compliant status matches project environmental requirements. Ensure the 8-Lead SOIC_N package dimensions align with the target PCB footprint layout constraints.
Selection Notes
Select this component when application demands combine high-speed signal processing with strict power consumption limits. The JFET input architecture is optimal for interfacing with high source impedance sensors. Verify that the ±4.5 V minimum supply voltage requirement fits the system power budget and available rails.
Part Context
This part belongs to the AD8682/AD8684 family of dual and quad low power, high speed JFET operational amplifiers. The series is engineered to deliver excellent dynamic performance while maintaining low supply currents, making it suitable for battery-powered or energy-constrained electronic systems requiring precision analog signal conditioning.
Replacement Considerations
Cross-reference with AD8682ARMZ-R2 for MSOP packaging variants. Evaluate OP282 or TLE2082 as potential functional equivalents for similar JFET input specifications.
