LM2901A-TS2R-S

Overview

The LM2901A-TS2R-S is a quad independent comparator from the 3PEAK LM2901A series, housed in a TSSOP14 surface-mount package. It operates on a single supply voltage ranging from +2.5 V to +36 V or dual supplies of ±1.25 V to ±18 V. The device features low input bias current with a maximum of 1 nA and low offset voltage up to ±7.0 mV. It supports direct interfacing with TTL and CMOS logic levels and includes open-collector outputs capable of wired-AND configurations. Qualified for automotive applications under AEC-Q100 standards, it functions reliably within an operating temperature range of −40°C to 125°C.

Feature Summary

• Automotive qualification compliant with AEC-Q100 reliability testing standards
• Wide supply voltage operation supporting both single and dual power sources
• Low power consumption suitable for battery-operated systems
• Input common-mode voltage range extends to ground potential

Applications

• High-speed line or digital line receivers
• Peak and zero-crossing detectors
• Infrared receiver circuits
• High-speed sampling circuits

Procurement Notes

Verify that the specific ordering suffix TS2R-S corresponds to the TSSOP14 package type and tape-and-reel transport media as defined in the manufacturer's order information table. Confirm that the component meets RoHS compatibility and halogen-free requirements specified by the supplier. Ensure design implementation accounts for the absolute maximum ratings regarding supply voltage and input current limits to prevent permanent damage.

Selection Notes

Select this component when a quad comparator configuration is required for space-constrained designs utilizing TSSOP14 packaging. It is appropriate for applications demanding direct interface with standard logic families without additional level shifting. Consider its low quiescent current characteristics for energy-sensitive environments. Validate that the open-collector output structure aligns with the system's pull-up resistor requirements and wired-AND logic needs.

Part Context

This part belongs to the LM2901A series of 36-V low-power comparators manufactured by 3PEAK. The series includes dual and quad variants available in various packages such as SOP, TSSOP, and MSOP. These devices are designed for general-purpose comparison tasks requiring high reliability and wide voltage tolerance. The LM2901A variant specifically integrates four independent channels on a single monolithic substrate.
