LM193, LM293, LM393 Low power dual voltage comparators Datasheet -production data Features Wide single-supply voltage range or dual supplies: +2 V to +36 V or 1 V to 18 V Very low supply current (0.45 mA) independent of supply voltage (1 mW/comparator at +5 V) Low input bias current: 20 nA typ. Low input offset current: 3 nA typ. Low input offset voltage: 1 mV typ. Input common-mode voltage range includes ground Low output saturation voltage: 80 mV typ. (Isink = 4 mA) Differential input voltage range equal to the supply voltage TTL, DTL, ECL, MOS, CMOS compatible outputs Available in DIP8, SO-8, TSSOP8, MiniSO-8, and DFN8 2 x 2 mm packages DIP8 (plastic package) SO-8 (plastic micropackage) TSSOP8 (thin shrink small outline package) Description The LM193, LM293, and LM393 devices consist of two independent low voltage comparators designed specifically to operate from a single supply over a wide range of voltages. Operation from split power supplies is also possible. These comparators also have a unique characteristic in that the input common-mode voltage range includes ground even though operated from a single power supply voltage.

At output switch point, Vo 1.4 V, Rs = 0 with VCC+ from 5 V to 30 V, and over the full common-mode range (0 V to VCC+ -1.5 V). 2. The direction of the input current is out of the IC due to the PNP input stage. This current is essentially constant, independent of the state of the output, so no loading charge exists on the reference of input lines. 3. Positive excursions of input voltage may exceed the power supply level. As long as the other voltage remains within the common-mode range, the comparator will provide a proper output state. The low input voltage state must not be less than -0.3 V (or 0.3 V below the negative power supply, if used). 4. The response time specified is for a 100 mV input step with 5 mV overdrive. For larger overdrive signals 300 ns can be obtained. 6/20 Doc ID 2164 Rev 13 LM193, LM293, LM393 Figure 3. Electrical characteristics Supply current vs. supply voltage Figure 4.
