Maximum input offset voltage is 7 mV at 30 V supply, and maximum input bias current is 0.25 µA at 5 V — both figures are worst-case limits, not typicals, so the design-in margin must be budgeted against the full temperature sweep. Quiescent current maxes at 1 mA per device, which keeps the thermal load low in the 8-SOIC package even when both comparators are switching continuously. ## Propagation delay and output drive Typical propagation delay is 1 µs — this is the speed floor for the comparator loop. For overcurrent trip circuits or zero-crossing detection below 100 kHz, the 1 µs delay is adequate; above that, a faster comparator family is needed. The open-collector output sinks 6 mA typical at 5 V.","metaTitle":"LM2903IDRDL Dual General Purpose Comparator, -40°C to 125°C","metaDescription":"Texas Instruments LM2903IDRDL dual general-purpose comparator.

Both are dual open-collector comparators in the same 8-SOIC footprint, but the LM2903IDRDL extends the temperature range to 125°C and the supply range to 30 V, where the LM393 is typically limited to 0°C to 70°C and 36 V maximum.
