LMV7219

Texas Instruments · Comparator · SOT-23-5

The LMV7219 is a high-speed comparator with 7 ns propagation delay and a push-pull rail-to-rail output that needs no pull-up. It runs from a single 2.7 V to 5 V supply, suiting zero-crossing detection, pulse shaping, and fast level triggering in a compact SOT-23-5.

Pinout

Pin Name Type Function
1 OUT output Comparator push-pull rail-to-rail output. Swings from V- to V+; 7 ns propagation delay, 1.3 ns rise/fall time; sourcing/sinking short-circuit current 20 mA.
2 V- power_in Negative supply pin. Tie to GND for single-supply operation; supply span (V+ - V-) is 2.7 V to 5 V (5.5 V absolute max).
3 +IN input Non-inverting comparator input. Common-mode range extends 200 mV below V- up to V+ - 1.2 V; input bias current 450 nA typical.
4 -IN input Inverting comparator input. Same common-mode range and bias-current characteristics as +IN; differential input voltage rated up to ±supply voltage.
5 V+ power_in Positive supply pin. 2.7 V to 5 V recommended (5.5 V absolute max); typical supply current 1.1 mA at 5 V (0.9 mA at 2.7 V).
