Part Number: PGA854 Other Parts Discussed in Thread: PGA848 , TINA-TI I can't seem to download the PGA854 TINA-TI Reference Design (SBOMCS8). It redirects me to a 404 page. This also applies to the PGA848.
I would really like to get these.
Thanks…
Part Number: PGA849 Other Parts Discussed in Thread: PGA854 , PGA848 , PGA855
Hello, I am designing a miniature cost optimized DAQ system using the PGA849 as part of its analog front-end. Given the PGA849 is limited to a 36V recommended operating common…

Dear Team,
We are currently working on an analog front-end design that includes a Programmable Gain Amplifier (PGA), a low-pass filter, and an Analog-to…
Part Number: PGA849 Other Parts Discussed in Thread: PGA848 , , OPA192 Hi TI,
There are 2 questions actually:
Looking at the quiescent current plot, it's about 4mA at 25degC: and the table spec is: I take the plot as the sum of input and output…
Part Number: INA129 Other Parts Discussed in Thread: PGA848 Tool/software: Hi everyone,
I'm working on a design where I need to measure the voltage drop across a current-sense resistor.
The sensor output is a differential signal with a typical range…
Hi Sizhou,
Thank you for posting on e2e.
I do not believe this will work.
I think in the suggested configuration, the current set resistor is completely bypassed. It also requires the excitation voltage for the circuit to be 1.235, which I am…
Hi Nithin,
Could you help me understand the design reasoning for using two stages with the programmable amplifier and a discrete difference amplifier with the LM324B? While I am not sure if this is the cause of the total 600mV offset, the second additional…
Janardan,
The OPA192 will work. See the document below for a potential implementation:

You can also use a fully differential amplifier:
