Overview
The AD8691AKSZ-R2 is a single-channel, low-cost, low-noise CMOS operational amplifier with rail-to-rail output. It operates on a single supply from 2.7 V to 6 V and features a gain-bandwidth product of 10 MHz and a slew rate of 5 V/µs. The device exhibits a typical input offset voltage of 400 µV, maximum input bias current of 1 pA, and voltage noise density of 8 nV/√Hz. It is qualified for automotive applications and functions within an extended industrial temperature range of −40°C to +125°C.
Feature Summary
- Rail-to-rail output capability for maximizing dynamic range in single-supply systems.
- Very low input bias current of 1 pA maximum suitable for high-impedance sensor interfaces.
- Low noise performance with 8 nV/√Hz voltage noise density.
- Automotive qualification ensuring reliability for demanding environments.
Applications
- Photodiode amplification
- Battery-powered instrumentation
- Medical instruments
- Multipole filters
- Portable audio devices
Procurement Notes
Verify the specific package option KS-5 (5-Lead SC70) matches the design footprint. Confirm RoHS compliance status as indicated by the Z suffix. Ensure the ordering suffix -R2 corresponds to the required reel quantity. Validate that the automotive grade specifications align with the target application requirements before finalizing procurement.
Selection Notes
Select this component when a single-channel amplifier with rail-to-rail output is required. It is appropriate for designs needing low noise and very low input bias currents. Consider the 5-Lead SC70 package for space-constrained layouts. Verify that the 10 MHz bandwidth meets the signal processing needs.
Part Context
This part belongs to the AD8691/AD8692/AD8694 family of low-cost, low-noise CMOS operational amplifiers. The AD8691 variant provides a single amplifier channel. The AKSZ suffix indicates the 5-Lead SC70 surface-mount package option. The family supports single-supply operation and is designed for precision applications requiring wide bandwidth.
Replacement Considerations
The AD8691AUJZ-R2 serves as a direct functional replacement using the 5-Lead TSOT package. Designers must verify pin compatibility and thermal characteristics between the SC70 and TSOT packages during substitution.
