Overview
The AD8667ARMZ is a dual-channel precision operational amplifier manufactured by Analog Devices Inc., housed in an 8-lead MSOP package. It features rail-to-rail output capability and operates on single supplies from 5 V to 16 V or dual supplies of ±2.5 V to ±8 V. Key electrical specifications include a maximum input offset voltage of 300 µV at 16 V, a supply current of 230 µA per amplifier, and a gain-bandwidth product of 540 kHz. The device maintains low noise performance with a voltage noise density of 23 nV/√Hz and extremely low input bias current of 0.3 pA.
Feature Summary
- Utilizes patented DigiTrim trimming technique for low offset voltage
- Rail-to-rail output provides increased dynamic range
- Low input bias current suitable for high impedance sensors
- Unity-gain stable operation
Applications
- Sensor front ends
- Transimpedance amplifiers
- Electrometer applications
- Photodiode amplification
- Medical diagnostic instruments
Procurement Notes
Verify the specific ordering suffix 'M' corresponds to the 8-lead MSOP package variant. Confirm RoHS compliance status indicated by the 'Z' suffix. Ensure the component matches the manufacturer's part number exactly to avoid pinout discrepancies with other packages in the AD8663/AD8667/AD8669 family.
Selection Notes
Select this component when low power consumption and precision are required for single-supply systems. The wide supply voltage range up to 16 V accommodates various industrial standards. Consider the 8-lead MSOP package for space-constrained designs requiring surface-mount installation.
Part Context
This device belongs to the AD8663/AD8667/AD8669 series of low noise, precision CMOS rail-to-rail operational amplifiers. The AD8667 specifically denotes the dual-channel configuration within this family, sharing core technologies like DigiTrim with the single (AD8663) and quad (AD8669) variants.
Replacement Considerations
Direct substitutes within the same package and function include AD8667ARZ (SOIC package) and AD8667ARMZ-REEL (tape and reel packaging). Verify pin compatibility if replacing with non-Analog Devices equivalents.
