Overview
The AD8659ARZ-R7 is a quad micropower, precision, rail-to-rail input/output CMOS operational amplifier. It operates from a single supply of 2.7 V to 18 V or dual supplies of ±1.35 V to ±9 V. Key electrical specifications include a maximum offset voltage of 350 μV, a maximum input bias current of 20 pA, and a gain bandwidth product of 230 kHz. The device draws a typical quiescent supply current of 18 μA per amplifier and maintains excellent electromagnetic interference immunity.
Feature Summary
- Utilizes DigiTrim trimming technique for low offset voltage
- Provides high immunity to electromagnetic interference
- Features rail-to-rail input and output capabilities
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 series includes both 14-lead SOIC and 16-lead LFCSP options. Confirm that the ordering suffix matches the required reel packaging format. Ensure the component meets the extended industrial temperature range requirements specified in the official documentation before integration.
Selection Notes
Select this component when designing circuits requiring low power consumption alongside high precision at elevated supply voltages up to 18 V. The combination of very low input bias current and rail-to-rail operation makes it suitable for interfacing with high impedance sources. Consider the 230 kHz bandwidth for applications requiring moderate speed without excessive power dissipation.
Part Context
This part belongs to the AD8657/AD8659 family of micropower precision amplifiers. While the AD8657 provides two channels, the AD8659 integrates four independent amplifiers within a single package. Both variants share identical electrical characteristics and are optimized for applications demanding low power and wide operating voltage ranges.
Replacement Considerations
The AD8657 serves as the dual-channel counterpart within the same family. Verify pin compatibility if substituting between different package types such as SOIC and LFCSP.
