Sourcing Guidance
AD620AN is a legacy or obsolete orderable code. Source only with date-code, label, package and traceability checks appropriate to the application.
For an accurate quotation, include the full MPN, target quantity, acceptable date-code range, packaging format and destination. Icearth can help review traceability documents, label photos and electrical/package alignment before order placement.
Manufacturer Documentation
Technical values were checked against Analog Devices documentation. Use the linked datasheet as the controlling source and re-check revisions before PCB release or firmware qualification.
AD620AN selection and design context
AD620AN is cataloged as a Instrumentation Amplifier in the AD620 family. Its recorded function is low-power precision instrumentation amplifier with resistor-programmable gain. Selection should be based on the complete electrical limits, package drawing and ordering suffix rather than the abbreviated family code.
- Supply Range: ±2.3 V to ±18 V. Check rail compatibility, tolerance and sequencing under worst-case conditions.
- Gain Range: 1 to 10,000. Confirm the value and its datasheet test conditions for the exact ordering suffix.
- Input Offset Voltage: 50 µV max, A grade. Check rail compatibility, tolerance and sequencing under worst-case conditions.
- Input Bias Current: 1 nA max. Check steady-state, transient and thermal margin in the intended operating mode.
Application and qualification considerations
When evaluating this signal-chain device, confirm channel count, input and output range, bandwidth, noise, distortion, supply rails and digital-interface format where applicable. For a new design, review power-up behavior, interface timing, absolute maximum ratings, thermal limits and any external-component requirements in the latest manufacturer documentation. Existing-board replacement work should additionally confirm pinout, footprint, firmware assumptions and qualification grade.
Procurement checks for AD620AN
The recorded package is 8-lead PDIP, the temperature range is -40°C to +85°C, and the lifecycle status is Obsolete as of 2026-07-18. Before ordering, confirm the exact MPN on the label, packing format, quantity, date-code requirements, traceability documents and current factory status.
AD620AN FAQ
What distinguishes AD620AN within the AD620 family?
