The right way to use instrumentation amplifiers

amps have excellent CMR (common-mode rejection), designers must limit the total common-mode voltage, plus the signal voltage, to avoid saturating the amplifier¡¯s internal inputbuffers. Unfortunately, they often overlook this requirement. Other common... EDN Asia
