The OPA2691's low 5.1mA/ch supply current is precisely trimmed at 25C. This trim, along with low drift over temperature, ensures lower maximum supply current than competing products. System power may be further reduced by using the optional disable control pin (SO-14 only). Leaving this disable pin open, or holding it HIGH, gives normal operation. If pulled LOW, the OPA2691 supply current drops to less than 150A/ch while the output goes into a high impedance state. This feature may be used for power savings.
