amplifier noise | Cypress Semiconductor
I am considering using a PSoC device as part of an instrumentation system, but am worried that the amplifier ac specs may not be up to the job. I need an instrumentation amp with gain of about 20-50, low bandwidth (up to 50kHz GBW) and low input noise (<5uV). The INSAMP quotes 0.75MHz GBW at 5V and a noise voltage input of about 100nV/rtHz, which would yield an input noise of 12uV at G=50. This is too high. Has anyone obtained actual noise figures for their similar designs please?
