Part Number: PGA281 Hi,
I did the circuit below.
The Gain set to 2, and VOCM set to 0V.
Then the ERROR_FLAG always set to HIGH level (3.3V) when applying the voltage to the INP(TP1) and INN(TP5)
Which the voltage between INP and INN goes from 0.1 to 0…
using a current of 1A to measure the output impedance of PGA281 is wayyyyyyyyyyyyyyyyy too high :-(
Keep in mind that the typical short circuit current of PGA281 is 15mA:
You have very probably damaged the PGA281 with this test...
Part Number: PGA281 Hi ,
I am using PGA281 where its input stage supply is 10 V single ended (i.e VSP=10 V & VSN=0V) and
Output stage supply is 3.3V (i.e VSOP=3.3 V & VSON=0V) & Logic supply is 3.3V (Different power from output stage supply…
Part Number: PGA281
Can you share more information about the test condition of PGA281 CMRR?
Below information in datasheet only shows power supply condition, Gain setting, Vcm=0 and temperature and CMRR vs signal frequency.
But customer need…
Part Number: PGA281
Can you advice me how to determine values for different filters of the DAC stage for the frequency range between 50KHz to 200KHz on PGA281?
To better visualize, one proposed value of your filter design was 87pF, this value is…
Thanks for providing these additional details.
Given your configuration, the PGA281 should work in your system. Please note that the input range of the PGA281 extends beyond the input range of the ADS1258 MUX. Therefore, as long as you are only…
Part Number: PGA281 Other Parts Discussed in Thread: TINA-TI Dear Marek, thank you
I opened PGA281 circuit in TINA-TI. Please, explain, what is the "VCS2" and "VCS4" elements at the input of the amplifier?
Please, see attach
Part Number: PGA281 Other Parts Discussed in Thread: OPA2320 Hi guys, I'm Jose.
I want to use the PGA281 . For VSOP = 2.5 V and VSON = -2.5V. When using a negative supply for VSON, the datasheets says "The negative digital supply is connected to the…
