Sourcing Guidance
AD698APZ 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.
AD698APZ selection and design context
AD698APZ is cataloged as a Sensor Interface IC in the AD698 family. Its recorded function is universal LVDT signal conditioner with synchronous demodulation. Selection should be based on the complete electrical limits, package drawing and ordering suffix rather than the abbreviated family code.
- Excitation Frequency: 20 Hz to 20 kHz. Confirm system timing margin and the test conditions attached to the published limit.
- Signal Input Range: 0.1 V RMS to 3.5 V RMS. Confirm the value and its datasheet test conditions for the exact ordering suffix.
- Output Voltage: Up to ±11 V. Check rail compatibility, tolerance and sequencing under worst-case conditions.
- Function: LVDT/RVDT signal conditioning. Confirm the value and its datasheet test conditions for the exact ordering suffix.
Application and qualification considerations
When evaluating this sensor, confirm measurement range, sensitivity, noise, output data rate, interface voltage, calibration needs and mechanical orientation. 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 AD698APZ
The recorded package is 28-lead PLCC, the temperature range is -40°C to +85°C, and the lifecycle status is Obsolete as of 2026-07-18.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.
AD698APZ FAQ
What distinguishes AD698APZ within the AD698 family?
AD698APZ is the exact orderable code for a universal LVDT signal conditioner with synchronous demodulation in 28-lead PLCC. Related AD698 devices may change package, rating, interface option or qualification grade, so compare the manufacturer ordering table before substitution.
What package and footprint checks are required for AD698APZ?
