Part Number: TLC4502 Dear Team -
We have built pH and Ammonia circuits leveraging TLC4502 IDR. The measurement recorded was accurate, and repeatability is good. However, after a few days to less than a month, IC is not reacting with the sensor. After…

I am looking a replacement for TLC4502. Any recomendations?
Thanks!
Joseph,
Joseph Wu said: In your schematic, you have several OPA1612s (U304, U305) listed in the circuit. Are these really the OPA2822s? Also, are they running at +5V single supply?
That was an old schematic. The module is equipped with 2 TLC4502…
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also looks like a good choice, this file has not been recently updated so the OPA196 is not in yet, and the pricing is out of date.

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…
