Overview
The ADA4665-2ARMZ-R7 is a dual-channel CMOS operational amplifier featuring rail-to-rail input and output capabilities. It operates on a single supply from 5 V to 16 V or dual supplies of ±2.5 V to ±8 V. Key electrical parameters include a typical gain bandwidth product of 1.2 MHz, a slew rate of 1 V/µs, and a maximum input bias current of 1 pA. The device draws 290 µA per amplifier at 25°C and maintains an operating temperature range of -40°C to +125°C.
Feature Summary
- Rail-to-rail input and output swing capability for maximizing dynamic signal range.
- Ultra-low input bias current of 1 pA maximum for high-impedance applications.
- Optimized low power consumption suitable for battery-operated systems.
- Unity-gain stable design with wide bandwidth.
Applications
- Portable systems
- Medical equipment
- Physiological measurement
- Sensor front ends
Procurement Notes
Verify the package type matches the required PCB footprint, as this part number specifies the MSOP variant. Confirm RoHS compliance status if environmental regulations apply to the manufacturing process. Ensure the ordering suffix corresponds to the reel quantity intended for production assembly lines.
Selection Notes
Select this component when designing circuits that require both low power consumption and full voltage swing near the supply rails. It is appropriate for applications needing high input impedance combined with moderate bandwidth. Consider thermal resistance values if multiple units are placed closely on the board.
Part Context
This device belongs to the ADA4665 family of precision amplifiers designed for low-power budget designs. It serves as a dual-channel alternative to single-channel variants like the AD8541. The MSOP package option provides a compact surface-mount solution for space-constrained electronic assemblies.
Replacement Considerations
The ADA4665-2ARZ is a pin-compatible leaded version of this component. Designers may also consider the ADA4091-2 for similar functionality in different package formats.
