Part Number: TIDA-00639 Other Parts Discussed in Thread: OPA333 Hi all,
the sense resistor needs to be small in comparison to R1 and others of the OPA333 circuitry. But what if I need to increase the sense resistor, if it is needed to measure small…
Hi Chase,
You have many options for this. Our shunt based devices (the INA series) can't typically handle that high of voltage on their own, but we have this reference design for the INA226 ( https://www.ti.com/tool/TIDA-00639 ) that allows you to…
Other Parts Discussed in Thread: TIDA-00639 Hello,
I understand that when we have high voltages in the circuit, isolated V and I measurement is necessary because of regulatory/safety requirements. However, still i could see some references suggesting…

I have a quirky academic device to design,
I will be be passing 0-150V at 1nA to 1mA through a piece of organic tissue.
I…
Part Number: OPA333 Other Parts Discussed in Thread: TIDA-00639 Hello,
Below is TIDA-00639 600-V Unidirectional Current sensing design. But I have one question as block diagram. Does OPA333 support 600V common mode range? Why 600V DC bus input OPA333…
