TS3121 and TS3121A: the ultimate solution for high-speed, low-power comparators
The TS3121 and TS3121A are advanced rail-to-rail, open-drain comparators designed for high-speed response with low power consumption and come in a compact size, making them ideal for space-constrained applications.
These comparators feature a low offset voltage of 2 mV max at 25 °C (A-grade), low power consumption of 70 μA typical while offering a fast propagation delay of 60 ns, fail-safe input/output, and a guaranteed start-up time.
Suitable for industrial and automotive applications, power tools, overcurrent protection, controllers and sensors, they operate over a wide supply voltage range (1.7 to 5.5 V) and temperature range (-40 °C to +125 °C).
