Part Number: TIDA-01527 Other Parts Discussed in Thread: TL431 , OPA322-Q1 Hello all,
I'm designing a resolver circuit for motor control, according to the reference design "TIDA01527" I have several questions.
Question 1: Why the DC biasing…

Dear Kai,
Thanks for your quick reply. I plan to use OPA322 with XTR115 (4-20mA cuurent loop transmitter). I hope OPA322 is unity gain.
Let me explain my design concept. It is a current measurement design. Primary current is passing through Current…
to User473,
I searched all the op amp portfolio with the parametric search (precision, general purpose, and high-speed). There are 6 options with temperatures of 150C and above (see attached). The best match is the OPA211-HT (210C max). This is the…
Hi Lucas,
Lucas Hölbling said: Is a load resistor to GND on the output required?
This technique is discussed in the datasheet of OPA364. See figure 24.
In the datasheet of OPA320 the use of a Schottky diode to generate a negative supply voltage…
The OPA145 also looks like a good choice, this file has not been recently updated so the OPA196 is not in yet, and the pricing is out of date.

The INA241 has high bandwidth and passes high-frequency noise. An output capacitor can reduce visible output noise. Large capacitors also attenuate fast current transients. Use an RC filter instead of only a capacitor. Try 100 ohm and 10 nF initially…
