Because of the Thanksgiving holiday in the U.S., TI E2E™ design support forum responses may be delayed from November 25 through December 2. Thank you for your patience.
Other Parts Discussed in Thread: INA219 , LPV812 , OPA320 , PGA206 Hi, im trying to build a ultra-low current reader using arduino and INA219 for my sensor device. Anybody can help me to explain whether it is possible to create ultra-low current sensing device…
Other Parts Discussed in Thread: PGA281 , PGA206 In an application case where only the IN-P is used for 0-5 Vdc input, and correspondingly only use VO-P, when VOCM is tied to VSON, can the PGA281 be used? I realize that the VO-N will saturate low and cause…
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…
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.
Sitara AM3357 will…
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…
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

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…
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…
