Part Number: PGA117 Other Parts Discussed in Thread: PGA460 , PGA308
Tool/software:
I filtered the list on the TI webstire for PGAs & VGAs and it seemed like the PGA117 has many of these features such as hardware/software shutdown, daisy chaining…
Part Number: PGA117 Hello Texas Instruments,
1) If AVDD and DVDD are both 3.3V same exact voltage regulator part number but two different parts. Could this be a problem? Page 41 says make AVDD above DVDD so V out does not raise AVDD. I assume they…
Part Number: PGA117 Other Parts Discussed in Thread: OPA325 , LM7705 , INA190 , INA851 , INA333 , TINA-TI Hello TI E2E,
I am attaching 3 screenshots with this post for clarity. I have a programmable current source that ranges from 0.5mA to ~6A. I…
Other Parts Discussed in Thread: PGA117 , LMP8358 Hello,
I currently have 4 LMP8358MTs connected to CH1, CH2, CH3, and CH4 of the PGA117. I am currently trying to test my LMP8358MT by sending 0x3a and 0x01 to tell the PGA117 to set the gain to 1 on…
Other Parts Discussed in Thread: PGA117 , PGA112 Hello,
On page 27 of the PGA117 family datasheet, it has SPI commands for the PGA112/113 and also daisy-chain commands but I don't see where it specifically states what commands I would use for the PGA117…
Other Parts Discussed in Thread: PGA117 Hello,
I see that you can shutdown the PGA117 via SPI. However, I couldn't find anything in the data sheet that states whether or not it is safe to apply any type of voltages if I either it shutdown via SPI or…
Hello Edmond,
I have a few suggestions for getting the PGA117 configured properly:
Make sure to provide the SPI /CS signal which remains low for the duration of each SPI command
Keep a logic "high" voltage applied to pin 13, ENABLE, to keep the…
Other Parts Discussed in Thread: PGA117 , PGA113 i need help to calculate volt and current measurement with pga117 ic where i want to measure 0 to +/- 1000 volt dc in one input and other input i want to measure 0 to +/- 10 ampere dc using shunt resistor…
Other Parts Discussed in Thread: PGA117 , PGA281 , PGA280 Hello,
Can someone suggest a suitable circuit for using PGA117 as a thermocouple amplifier. The input may go down to
-10mV. Will a bias on Vref pin and connecting the T/C between Vref and an…
