AD8668ARUZ

Overview

The AD8668ARUZ is a quad, low-cost, low-noise operational amplifier from Analog Devices. It features rail-to-rail output and operates on single supplies from 5 V to 16 V or dual supplies of ±2.5 V to ±8 V. Key electrical parameters include a gain-bandwidth product of 4 MHz, a slew rate of 3.5 V/µs, an input bias current of 1 pA maximum, and a voltage noise density of 8 nV/√Hz at 10 kHz. The device is housed in a 14-lead TSSOP package 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
Low input bias current suitable for high-impedance sensor interfaces
Wide supply voltage operation up to 16 V
Unity-gain stable with low noise performance

Applications

Sensor amplification
Photodiode amplification
ADC drivers
Medical equipment signal conditioning
Reference buffers

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm the package type and RoHS compliance status. Confirm that the intended application environment falls within the specified operating temperature range of −40°C to +125°C. Ensure power supply rails do not exceed the absolute maximum ratings defined in the datasheet to prevent permanent damage.

Selection Notes

Select this component when a cost-effective solution with rail-to-rail output and low noise is required. It serves as a direct replacement for higher-priced JFET amplifiers in applications demanding low input bias currents. Consider the 4 MHz bandwidth and 3.5 V/µs slew rate for general-purpose signal processing tasks.

Part Context

The AD8668ARUZ belongs to the AD866x family of precision amplifiers designed for single-supply operation. This family includes variants like the AD8665 and AD8666, which offer different channel counts and packaging options. The AD8668 specifically integrates four independent amplifiers into a compact 14-lead TSSOP footprint.
