Linear Comparators

LM2901D Description

The LM2901D is a general-purpose comparator designed and manufactured by STMicroelectronics. This IC is housed in a surface-mount 14SO package, making it suitable for a wide range of applications where space is a critical consideration. The LM2901D features four independent comparators, each capable of operating with a supply voltage range of 2V to 32V for single supply and ±1V to ±16V for dual supply configurations. This wide voltage range ensures compatibility with various power supply systems.

The LM2901D offers a typical output current of 16mA at 5V, making it suitable for driving moderate loads directly. Its quiescent current is kept low at a maximum of 2.5mA, which is beneficial for applications where power consumption needs to be minimized. The input bias current is also remarkably low, with a maximum of 0.25µA at 5V, ensuring minimal loading on the input sources.

The input offset voltage is a critical parameter for comparators, and the LM2901D maintains a maximum input offset voltage of 7mV at 5V. This low offset voltage ensures high accuracy in signal comparison. The LM2901D is REACH unaffected and RoHS3 compliant, making it environmentally friendly and suitable for use in regions with strict environmental regulations.
