TPMC151 4 Channel Resolver or LVDT/RVDT to Digital Converter

The TPMC151-10R provides 4 channels of Resolver or LVDT/RVDT to Digital Converter with 16-bit resolution. It accepts inputs signals up to 12 VRMS, with frequencies ranging from 1 kHz to 20 kHz and allows tracking rates up to ¼ of the excitation frequency (i.e. 10 kHz -> 2500 rps). The converter provides a digital angle, respectively stroke value, and a digital velocity value. For LVDT/RVDT differential and ratiometric sensor configuration is supported.
The TPMC151 provides individual excitation outputs with software selectable excitation frequency and output voltage swing for each channel. Adjustable frequency is ranging from 1 kHz to 20 kHz and the output voltage range is 0 to 12 VRMS with up to 100 mA. No external power supply is required. Alternatively, an external excitation can be used.

The TPMC151-20R replaces two resolver channels with two Synchro-to-Digital Converter channels. For Synchro channels the excitation output is not available and an
external excitation must be used. Synchro channels accept input signals up to 28 VRMS, with frequencies ranging from 400 Hz to 20 kHz.

All TPMC151 signals are accessible through a 50-pin MDR type front I/O connector.

A wide range of drivers is available: Linux, Integrity, QNX, VxWorks and Windows. All drivers - except the Windows drivers - are supplied as C source code.
