AD8220ARMZ-RL

Instrumentation, Op Amps, Buffer Amps Overview

The AD8220ARMZ-RL is a JFET input instrumentation amplifier in an MSOP package. It features a minimum CMRR of 86 dB at DC and 80 dB at 5 kHz for G=1. Input bias current is 10 pA maximum, with 14 nV/√Hz noise at 1 kHz. Bandwidth is 1.5 MHz at G=1. Supply range is 4.5 V to 36 V single or ±2.25 V to ±18 V dual. Quiescent current is 750 μA max. Gain is set by one resistor (G=1 to 1000). Operating temperature is -40°C to +85°C.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• JFET inputs provide extremely low bias currents and high input impedance
• Rail-to-rail output stage maximizes dynamic range on low voltage supplies
• Single-resistor gain setting simplifies circuit design from G=1 to 1000
• Reference pin allows user offsetting of the output voltage

• Transducer interfaces

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'ARMZ' corresponds to the A-grade industrial temperature rating (-40°C to +85°C) rather than the W-grade automotive rating. Confirm the reel packaging matches system requirements. Cross-reference the manufacturer part number against official Analog Devices documentation to ensure authenticity and correct revision status before integration.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when low input bias current and high common-mode rejection are required in a compact surface-mount package. The rail-to-rail output is suitable for single-supply portable applications. Ensure the gain resistor selection maintains stability within the specified bandwidth limits for the desired signal frequencies.

Instrumentation, Op Amps, Buffer Amps Part Context

This device belongs to the AD8220 family of instrumentation amplifiers. It is distinguished as the first single-supply JFET input version available in an MSOP package. The ARMZ variant specifically denotes the A-grade performance level optimized for general industrial and portable instrumentation tasks.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

AD8220BRMZ-RL offers B-grade specifications with tighter CMRR and offset parameters. AD8220WARMZ-RL provides extended temperature operation up to +125°C for automotive environments. Verify pin compatibility and thermal characteristics when substituting.
