The OPA314 is designed into a strain-gauge monitor and performs to the requirements, however, the Iq is too high. Would like a drop-in replacement wit lower Iq, and the following characteristics:
- GBW 1.5MHz>3MHz
- Total Supply Voltage 2V
- Noise <14nV/sqrt(Hz) at 1kHz
- Internal RF/EMI filter
- -40C > 125C operating
- and the most difficult(?) Iq < 150uA
Using the COMPARE function on the OPA314 page, I have not found any other device to meet these requirements, the TLV314 comes close.
Am I missing something, or there is not a device that will meet these requirements?
