Overview
The AD8659ARZ-RL is a quad micropower, precision, rail-to-rail input/output operational amplifier manufactured by Analog Devices. It operates from a single supply of 2.7 V to 18 V or dual supplies of ±1.35 V to ±9 V. The device features a maximum offset voltage of 350 μV and a maximum input bias current of 20 pA at 25°C. It achieves a gain bandwidth product of 230 kHz and unity-gain crossover of 230 kHz. Typical quiescent supply current is 18 μA per amplifier, with a maximum of 22 μA. The component is specified over an extended industrial temperature range of −40°C to +125°C.
Feature Summary
- Utilizes DigiTrim trimming technique for low offset voltage
- Offers high immunity to electromagnetic interference
- Supports wide operating supply voltage ranges
Applications
- Portable operating systems
- Current monitors
- 4 mA to 20 mA loop drivers
- Buffer/level shifting
- Multipole filters
Procurement Notes
Verify the specific package configuration against the datasheet, as the AD8659 is available in both 14-lead SOIC and 16-lead LFCSP packages. Confirm that the ordering suffix corresponds to the reel packaging format required for your assembly process. Ensure compatibility with the intended supply voltage range and temperature specifications before finalizing procurement.
Selection Notes
Select this component when designing circuits requiring low power consumption alongside high precision. The combination of very low input bias current and rail-to-rail operation makes it suitable for high impedance input sources. Consider the specific package availability and thermal resistance characteristics relevant to your board layout constraints.
Part Context
The AD8659 belongs to the AD8657/AD8659 family of micropower precision amplifiers. While the AD8657 provides a dual-channel configuration, the AD8659 offers four channels within a single package. Both devices share identical electrical characteristics and are optimized for applications demanding low power and wide supply voltage flexibility.
Replacement Considerations
The AD8657 serves as the dual-channel counterpart within the same family. Other members of the precision micropower op amp series may offer similar performance profiles but differ in channel count or package options.
