Part Number: OPA2342 Tool/software: Hello TI team,
We are in the process of modifying our existing thermocouple acquisition circuit using the image below. The difference b/w the previous design and the present design is that we have introduced the…
Part Number: OPA2342 Other Parts Discussed in Thread: OPA2832 Hello expert,
We would like to search for replacement with MAX4017ESA and I found out OPA2342 could be a suitable part for it. But looked into the closed loop gain, I found out MAX4017ESA…
Part Number: INA126 Other Parts Discussed in Thread: OPA2342 , TLV3201 , Tool/software: Hi TI team,
We are using INA126, TLV3201, and OPA2342 for thermocouple measurements. The thermocouple output is fed into the INA126 input (0.951mV). The gain is…
Hi Manjunath,
Sorry about the delayed response. The above circuit looks good. Is the purpose of R9 and R10 to create a simple voltage division? If so, please note that for an input signal of 3.3V, the actual input to the non-inverting input of the…
Adding to Ralphs various questions; Have you tried to enable hardware oversampling or adjusted Tsh value for matching impedance OPA2342 of the ANIx input. Alternatively have you tired 2MSPS sample rate after adjusting the ADC clock divisor for 32Mhz.…
Other Parts Discussed in Thread: OPA2342 Hello analog gurus,
For my project I want to use two FSR to sense the user's feet. A Force Sensitive Resistor has a rest resistance of a couple of Megohms, it decreases quickly to a couple hundred ohms when a…
Feedback resistor acts as a load at the op amp's output; therefore, the higher resistor value than the typical specified in the datasheet should not be a problem; it is a lower value resistance that may be a problem if the output cannot drive it due to…
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…
