This datasheet introduces the characteristics of LM193, LM193A, LM293, LM293A, LM393, LM393A low power dual voltage comparators, including wide single-supply voltage range or dual supplies: +2V to +36V or ±1V to ±18V, very low supply current (0.4mA) independent of supply voltage (1mW/comparator at +5V), low input bias current: 25nA typical. Low input offset current: ±5nA typical. Low input offset voltage: ±1mV typical. Input common-mode voltage range includes ground. Low output saturation voltage: 250mV typical (Io = 4mA). Differential input voltage range equal to the supply voltage. TTL, DTL, ECL, MOS, CMOS compatible outputs
The LM193, LM193A, LM293, LM293A, LM393 and LM393A comparators are designed for low‑power operation across a wide single‑supply voltage range (+2 V to +36 V or +1 V to +18 V). They feature very low supply current (0.4 mA), low input bias current (25 nA typ.), low input offset voltage (+1 mV typ.) and low output saturation voltage (250 mV typ.).
These devices are offered in several plastic packages such as DIP‑8, SO‑8, TSSOP‑8 and Mini‑SO‑8, and operate over temperature ranges from –55 °C to +125 °C (depending on the part). Detailed electrical characteristics, absolute maximum ratings and typical application circuits are provided in the document.
