PGA900: About RATIOMETRIC BRIDGE EXCITATION

Part Number: PGA900
Other Parts Discussed in Thread: PGA300, PGA305

Hi,

Our customer is considering PGA900.
Can I check the details of BRIDGE EXCITATION before requesting a Full Datasheet?
For reference, I looked at the PGA300 data sheet.
・ Vout (not current source)
・ 2.5 / 2.0 / 1.25V MUX
Is this configuration the same as PGA900?

Best regards,

Hiroshi

Hello Hiroshi-san,

Yes, the PGA300 uses the same bridge excitation circuitry, so the available VBRG options are the same between it and the PGA900. I would recommend your customer look at the PGA300 or PGA305 first just in case it will provide what they need for their application. They include compensation and nonlinearity algorithms that remove the need to develop firmware and speed up development time.
