  RE: OPA2180: Why don't only OPA2180 support -40C to 125C?

  Hello Asaishi-san, The OPA2180 will operate with an ambient temperature of -40 to 125C, as specified in the recommended operating conditions. The specs where you see an ambient temperature range of -40 to 105C, such as input bias current, indicate...
