Part Number: PGA281 Hi,
I would like to implement the analog input front-end solution explained in the SBAA551 application note with the PGA281 amplifier: www.ti.com/.../sbaa551.pdf
This would allow me to go directly to my MCU AD converter and set the gain…
Part Number: PGA281 Dear Sirs,
I will use 4 PGA281 to amplify 4 different inputs. Can I connect the gain selection pins of all PGA281 together (G0:G4)? And the VOCM pin can I do it too? (like schematic bellow)
Best Regards
If VSP power up before VSOP supply will cause large VSOP current about(60~70mA), as shown in figure.(yellow: IN-N; green: IN-P; pink: VSOP current; blue: VOP-VON). A lot of PGA281 power up at the same time will cause VSOP supply source current protection…
Part Number: PGA281 Other Parts Discussed in Thread: PGA280 , PGA206 , INA851 My circuit function is to measure 0-7.4A current. Pga281 is used for current sampling, and the accuracy shall not be higher than 500uA. Since pga281 is out of stock, I hope to…

Since PGA281 is out of stock now, it is necessary to find an alternative.
Is there any recommended circuit scheme using operational amplifier or instrument amplifier?

Hi!
Instead of VSP=15V, VSN=-15V, is there any problem in operation even when ㅣ VSP+ㅣ>ㅣVSN-ㅣ?
What is the V- acceptable value relative to V+?
Can ㅣV+ㅣ and ㅣV- ㅣbe different when using general…
Part Number: PGA281 Hi,
I have a problem with my PGA281 circuit. I have four of them on the PCB. And some are defect right at the beginning.
Input is 0V and VOSM is 1,5V. In normal operational the output on VON and VOP are 1,5V. But with the defect PGAs…
Part Number: PGA281 Other Parts Discussed in Thread: THP210 , PGA206 , PGA207 Is there a product like PGA281 that can accept input signals of130Khz as well?
We need a high-precision instrumentation amplifier, for very low input signals.
The secondary requirement…
