# AD698AP (Component) ## Description LVDT Signal Conditioner IC – Converts half-bridge, 4-wire LVDT, and RVDT sensor signals into a unipolar or bipolar DC voltage proportional to position. The Analog Devices AD698AP integrates an excitation oscillator, voltage reference, synchronous demodulation, and ratiometric signal conditioning. It supports 20 Hz to 20 kHz excitation, up to 24 V RMS differential excitation, 0.05% linearity, and ±11 V output. The AD698AP is supplied in a 28-PLCC surface-mount package. #AnalogDevices #AD698AP #LVDT #SignalConditioner #PositionSensor #RVDT #SensorInterface #AnalogIC #Instrumentation ## Component Details - **Owner:** silicon-yard - **Created:** 8/11/2026 - **Last Updated:** 8/11/2026 - **Visibility:** Public - **Manufacturer Part Number:** AD698AP - **Datasheet URL:** https://storage.googleapis.com/graviton-electric-symbols/document_assets/user-uploaded/16d269f6e3ee6b60d81197ba7e61ac0b0f9e33cde3c1c26dbb7c9e3a482d07a4.pdf - **Manufacturer Name:** Analog Devices - **Symbol Style:** parametric-v1 - **Part Type:** Integrated Circuit - **Part Type:** Integrated Circuits - **Sub-Type:** Logic - **Manufacturer:** Analog Devices - **MPN:** AD698AP - **Mount Type:** Surface Mount - **Package / Case Code:** TO - **Pin Count:** 28 - **Logic Function:** AND ## Pins | Pin | Name | Type | |-----|------|------| | 28 | +VS | | | 3 | EXC2 | | | 2 | EXC1 | | | 7 | FREQ1 | | | 6 | LEV2 | | | 5 | LEV1 | | | 8 | FREQ2 | | | 10 | BFILT1 | | | 11 | BFILT2 | | | 13 | -BIN | | | 14 | +BIN | | | 15 | -AIN | | | 16 | +AIN | | | 20 | AFILT1 | | | 18 | -ACOMP | | | 19 | AFILT2 | | | 17 | +ACOMP | | | 27 | OFF1 | | | 22 | FEEDBACK | | | 26 | OFF2 | | | 23 | SIG | | | 21 | OUTFILT | | | 24 | SIGREF | | | 9 | NC_3 | | | 12 | NC_4 | | | 4 | NC_2 | | | 25 | NC | | | 1 | -VS | | --- *Generated from [https://www.flux.ai/silicon-yard/ad698ap](https://www.flux.ai/silicon-yard/ad698ap)*
