Part Number: OPA547EVM Other Parts Discussed in Thread: OPA547 Dear TI engineers
I would like to use the improved Howland circuit using the OPA547EVM PCB. my purpose is to drive a MEMS resistor of a few ohms typically from 10 to up to 500 ohm or even…
Part Number: OPA547EVM Other Parts Discussed in Thread: OPA547 following my previous request , i d like to drive current between 10 to 200 mA to heat up in AC a few ohm resistor. thanks
Part Number: OPA547EVM Other Parts Discussed in Thread: OPA547 , OPA548 , OPA548EVM Dear Thomas
I used the OPA 548 to test the improved Howland circuit designed in figure 10 page 16 of the datasheet sbou132.pdf. using the same settings and resistance the…
Hello Alex,
Regarding your questions:
1. can I use the Improved Howland Current Pump Configuration Setup in order to answer my experiment needs.
Yes, but you will need to use the OPA548 for the 1 Amp output current.
2. the user guide has a BOM…
What EVM? (The OPA547EVM, OPA548EVM, and TIPD138 reference design all use the T package.)
The chip is the same, but the EVM does not have any guarantees or qualifications.
Part Number: OPA551 Other Parts Discussed in Thread: DIYAMP-EVM , OPA547EVM Hello,
My customer needs a way to evaluate the OPA551. Is there an eval board or demo board for it (i didn't see one on ti.com) or is there a board they can modify for their testing…
