The LM339B and LM2901B devices are the next generation versions of the industry-standard LM339 and LM2901 comparator family. These next generation B-version comparators feature lower offset voltage, higher supply voltage capability, lower supply current, lower input bias current, lower propagation delay, and improved 2 kV ESD performance and input ruggedness through dedicated ESD clamps. The LM339B and LM2901B can drop-in replace the LM239, LM339 and LM2901, for both "A" and "V" grades.
All devices consist of four independent voltage comparators that are designed to operate from a single power supply over a wide range of voltages. Quiescent current is independent of the supply voltage.

The amplifier performance development kit (PDK) is an evaluation module (EVM) kit to test common operational amplifier (op amp) parameters and is compatible with most op amps and comparators. The EVM kit offers a main board with several socketed daughtercard options to fit package needs, allowing (...)
This is a low-cost, flexible voltage supervisor that uses a voltage reference in order to test the voltage of a battery. This solution can also be used as a voltage rail monitor for many applications that require accurate power delivery with multiple rails. With TI's ultra-low power voltage (...)
