Overview
The LM2901VDTBR2G is a quad comparator manufactured by onsemi, housed in a 14-TSSOP surface-mount package. It operates with single supply voltages from 3.0 V to 36 V or split supplies from ±1.5 V to ±18 V. The device features low input bias current of 25 nA (typical) and low input offset voltage of ±7.0 mV (maximum). It supports open-collector outputs compatible with TTL and CMOS logic families.
Feature Summary
- Supports both single and split power supply configurations for flexible system integration
- Features low input bias current and low input offset voltage for accurate signal comparison
- Includes ESD protection clamps on inputs to enhance operational reliability
- Outputs are compatible with standard TTL and CMOS logic levels
Applications
- Level detection circuits
- Low-level sensing applications
- Memory circuit designs
Procurement Notes
Verify the complete part number includes the suffix 'G' for lead-free compliance. Confirm the 'DTB' suffix corresponds to the TSSOP-14 package variant. Ensure the 'V' designation matches the extended temperature range requirements for your specific application environment before finalizing procurement.
Selection Notes
Select this component when high gain and wide bandwidth are required for fast response times. Consider the TSSOP-14 package for space-constrained PCB layouts. Verify that the open-collector output architecture aligns with the pull-up resistor requirements of your downstream logic interface.
Part Context
This device belongs to the LM2901 family of single-supply quad comparators. It shares functional similarities with the LM339 and LM239 series but offers specific electrical characteristics tailored for consumer, automotive, and industrial electronic applications requiring robust performance across varying temperature conditions.
