Four-channel synchronous vibration sensor interface reference design
TIDA-010249
Overview
This reference design explains the theory, design and testing of a synchronous, four-channel wideband high-resolution interface. The main targets are the vibration sensing applications, but the design can also be applied to any application that requires wideband, such as three-phase voltage and current monitoring in power factor measurement.
Features
- Synchronous four-channel wideband integrated electronic piezoelectric (IEPE) sensor interface
- 24-bit 20-kHz bandwidth conversion
- Data rate of 124 kSPS (daisy chain), 1 MSPS (parallel SPI)
- ±10-V AC input and 320-kΩ input impedance
- Onboard four excitation current (about 3.5 mA)
- Onboard non-isolated 5-V to 24-V boost
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
