The output stage accepts CMOS, MOS, open-drain, or TTL logic levels — the open-drain option lets multiple comparators wire-OR on a shared pull-up, common in over-voltage or window-detection banks. Input offset voltage is 2 mV max at 30 V supply — this sets the threshold uncertainty for a zero-crossing or level detector. A 2 mV offset on a 10 mV signal is a 20 % error; for precision thresholding below 50 mV, a trim resistor or a lower-offset comparator family is worth considering. That is low enough for a 10 kΩ source impedance (2.5 mV drop) but significant into a 1 MΩ sensor — the bias current times the source resistance adds a DC error that looks like an offset shift. For high-impedance front-ends, the bias current floor matters more than the offset voltage. Quiescent current maxes at 2.5 mA for both comparators — about 1.25 mA per channel. In a multi-comparator bank on a 24 V always-on rail, the quiescent draw adds up; eight LM393ADR devices pull 20 mA just sitting there, which may matter in loop-powered or battery-backed designs. Output current is rated 20 mA typical — enough to drive a logic input, an LED indicator, or a small relay coil through a series resistor. Driving a 50 Ω transmission line or a high-current load requires a buffer stage. ## Active lifecycle and compliance documentation It is ROHS3 compliant; no exemption-based restrictions apply to the plating or molding compound. For extended or automotive temperature ranges, the LM393 family includes industrial-grade siblings with -40°C to +125°C ratings — the package and pinout are identical, so a BOM swap does not require a board spin. ## Sourcing and availability The LM393ADR is sourced through independent distribution channels.","metaTitle":"Texas Instruments LM393ADR Dual Differential Comparator","metaDescription":"Texas Instruments LM393ADR dual differential comparator, 8-SOIC package.
