Overview
The LMV7235, produced by Texas Instruments, is an ultra-low power, low voltage comparator designed for high-speed applications. This device operates over a full supply voltage range of 2.7 V to 5.5 V, making it ideal for single-supply systems. The LMV7235 achieves a propagation delay of 75 ns while consuming only 65 µA of supply current at 5 V, making it highly efficient for power-sensitive designs. It is available in space-saving packages such as the 5-pin SOT-23 and 5-pin SC70, which are crucial for systems where size and power consumption are critical factors.
