PGA411QPAPRQ1

Jacob,

The PGA411-Q1 is indeed a custom part that is still in production. I will check on how to order the device and will update this thread by COB Tuesday.

If you need a resolver interface, we recommend a discrete solution over the PGA411.
The discrete reference design - TIDA-01527 - can be found here.

If you are not tied to using a resolver, we recommend the LDC5072-Q1, an inductive sensor for monitoring motor position and speed.
The LDC5072-Q1 uses inexpensive conductive target and sense coils fabricated using PCB technology.
No expensive resolver is required.
You can download and install sensor design tool that will allow you to enter mechanical and electrical requirements, and will then create a sensor & target design and then export your design as Gerber files. The tool can also create a Pspice model and test bench, which allows you to simulate your design in PSPICE-FOR-TI, a free Spice simulator.
