Title: Re: Pressure sensor Post by: free on March 10, 2008, 10:00:03 22:00 Using Instrumentation Amplifier(InAmp) chip is better than build InAmp from general purpose opamp(GPO).
I tried build from GPO with 1% resistors, but the result is not satisfy, the gain is too far from what I want. Title: Re: Pressure sensor Post by: POWERMAN on March 11, 2008, 09:16:04 09:16 Hi,
i using this schematic for MPX2010D and is work fine, i do correction parameters (offset and range) with autocalibration by soft. Instrument amplifier is better, yes, but more expensive too. All depend about application goals. regards. Title: Re: Pressure sensor Post by: anemon06 on March 11, 2008, 11:41:10 11:41 http://www.sonsivri.com/forum/index.php?topic=10598.msg45424#msg45424
