LMP91002: Deep sleep mode?

Part Number: LMP91002

I am struggling to find information on how deep sleep mode differs from standby mode. I suppose the main question is, is the control amplifier kept on in deep sleep? We want to take measurements maybe once per minute, but would be happy to have the TIA power down if possible. Minimal power is critical.

    Hello Stephen,

    In Standby state the Control Amplifier is power ON v/s Deep Sleep where it is powered down. This allows for a faster sensor response as the Bias is ON for the sensor cell. As a result the Standby state uses more current that Deep Sleep state. Hope this information helps.
