onsemi Comparators LM2901M

The LM2901M is a low-power, low-offset voltage quad comparator designed for precision voltage comparison applications. It operates from a single power supply with a voltage range of 2 to 36 V DC or ±1 to ±18 V DC, making it versatile for various circuit designs. The device features a maximum input offset voltage of 3 mV, low input bias current of 25 nA, and a low supply current of 0.8 mA, which is independent of the supply voltage. The input common-mode voltage range includes ground, allowing for operation close to zero volts, which is beneficial in many applications. The LM2901M is compatible with TTL, DTL, ECL, MOS, and CMOS logic systems, making it suitable for interfacing with a wide range of digital circuits. It is ideal for applications such as limit comparators, analog-to-digital converters, and various timing circuits. The device is housed in a 14-SOP package, facilitating easy integration into compact designs.
