7.4.1 Power-Down Mode

The OPAx863A includes a power-down mode for low-power standby operation with a quiescent current of 8.5 μA (typical) and high output impedance. Many low-power systems are active for only a small time interval when the parameters of interest are measured and remain in low-power standby mode for a majority of the time, for an overall small average power consumption. The OPAx863A enables such low-power operation with quick turn-on within less than 8 μs. See the Electrical Characteristics tables for power-down pin control thresholds.

The OPAx863A is enabled with the PD pin driven to VS+ – 0.5 V or greater. The device powers down if the PD pin is driven to VS+ – 1.5 V or less with a driver device capable of sinking approximately 1 μA (typical) current from the PD pin. If level translation is needed to realize the PD pin thresholds for enable or power-down modes of operation, use an external pullup resistor from PD pin to VS+ driven with an open-collector output.
