Description

The AD698 is a monolithic LVDT (Linear Variable Differential Transformer) signal conditioner from Analog Devices. It simplifies LVDT interfacing by providing excitation voltage, signal demodulation, and output amplification in a single IC.
Key features:
- Dual synchronous demodulation for accurate position measurement.
- Adjustable excitation frequency (20Hz–20kHz) and amplitude.
- Ratometric operation reduces sensitivity to excitation variations.
- Single or dual-supply operation (±5V to ±15V).
- Output voltage proportional to LVDT core displacement.
Applications include industrial automation, aerospace, and robotics, where precise linear position sensing is critical. The AD698 eliminates the need for complex external circuitry, offering a compact, reliable solution for LVDT-based systems.
For detailed specs, refer to the datasheet or Analog Devices' resources.

Equivalent

The AD698 chip, a signal conditioner for LVDT/RVDT sensors, has several equivalents:
1. AD598 – Similar functionality but older.
2. LVDT Signal Conditioners from Texas Instruments (e.g., PGA970).
3. MAX1452 (Maxim Integrated) – For sensor signal conditioning.
4. ZXL380 (Zetex) – LVDT signal conditioner.
For exact replacements, check datasheets for compatibility.

Pinout

The AD698 is a 20-pin IC designed for LVDT (Linear Variable Differential Transformer) signal conditioning. Key functions include:
- Pin Count: 20 (DIP or SOIC package)
- Primary Functions:
- Excitation output for LVDT (pins 4, 5, 6)
- Signal conditioning for LVDT secondary outputs (pins 1, 2, 3, 20)
- Ratometric demodulation (pins 7, 8, 9)
- Filtering and amplification (pins 10–14)
- Reference and power supply (pins 15–19, ±15V typical)
It converts LVDT positional data into a DC voltage proportional to displacement, with high accuracy and minimal external components.
