AD698 - Universal LVDT Signal Conditioner

Description

The AD698 is a complete, monolithic Linear Variable Differential Transformer (LVDT) signal conditioning subsystem.

It is used in conjunction with LVDTs to convert transducer mechanical position to a unipolar or bipolar dc voltage with a high degree of accuracy and repeatability.

Features

  • Single Chip Solution, Contains Internal Oscillator and Voltage Reference No Adjustments Required Interfaces to Half-Bridge, 4-Wire LVDT DC Output Proportional to Position 20 Hz to 20 kHz Frequency Range Unipolar or Bipolar Output Will Also Decode AC Bridge Signals Outstanding Performance Linearity: 0.05% Output Voltage: ؎11 V Gain Drift: 20 ppm/؇ C (typ) Offset Drift: 5 ppm/؇ C (typ) Universal LVDT Signal Conditioner AD698.
