Hi Bryan
Thanks for the reply I will explain the circuit further I refer to page 42 (figure 54. Multichannel, + -10V single-Ended input, Bipolar Supply Operation) of the ADS1158 datasheet.
-I will put 9K and 1K resistors in the analog input stage…
The attached presentation is where much of the methods for choosing the right R-C and Op Amp to drive a CDAC SAR converter were derived from. Look it over to help understand where the rules of thumb for op amp BW came from.
Let us know after studying…
Other Parts Discussed in Thread: INA121 , OPA192 Hello,
I'm working on a project where I have to design an amplifier and a filter for a sensor. The sensor is a hydrophone and this generates a differential voltage proportional to movement in water. It…
HI User,
Please find attached "The Instrumentation Amplifier Handbook", by Neil P. Albaugh from the Burr-Brown days a few years back. The handbook discusses several topics related to instrumentation amplifiers that are quite useful today.
On the section…
Hi A,
synchronous detection (alias phase sensitive detection or synchonous demodulation) can be performed this way:

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…
