Other Parts Discussed in Thread: PGA206 , TINA-TI , PGA204 I need a TINA-TI model for the PGA204. I tried modifying the PGA206, but it didn't work for the higher gains. I gave up rather than continuing to try to model.
Is there a PGA204 model out there…
Other Parts Discussed in Thread: ADS8332 , AM3357 , PGA204 , PGA206 , PGA205 , OPA192 , INA114 , OPA320 Hi,
I am planning to use two ADS8332 to sample a total of 16 single-ended channels and I have a few questions before I select the ADC.

Hello Adzhri,
The INA219 will not work for this application because the input bias current (~20uA) is of the same magnitude of the current you're trying to measure. I recommend using an op amp with a small input bias current. While the LPV812 does…
Hello Sakthi,
There are several PGA options that may meet your requirements. Unfortunately none of the options have as many gain steps as the PGA281, but perhaps you'll find one that includes the gains and bandwidths your system is requiring.
Take…
Hello Paolo,
Detecting such a wide range of current is definitely challenging, especially given 1MHz BW. The options we typically see are either changing the gain of the device (e.g. using a PGA as in TIPD135) or switching in different sense resistors…
Hiren,
It looks like the PGA206 has Pspice and TINA models available at the URL: http://www.ti.com/product/pga206&lpos=Middle_Container&lid=Alternative_Devices#simulationmodels

Hi Brad, if you need a simpler wide band PGA then you could consider the PGA206/207 or PGA103 from TI or Analog Devices AD8250/1/3 series. These parts are very simple to use, with 2 TTL level inputs used to set the gain. Min gain is 1 for each device…
Hello Dennis,
Thanks for the additional information concerning the various gains you're using. I'm assuming you mean 0dB to 40dB in 20V/V increments. That would correspond to 1V/V, 20V/V, 40V/V, 60V/V, 80V/V, and 100V/V. I was hoping to find a PGA…
