Overview
The LM2901AT14-13 is a quad differential comparator from Diodes Incorporated, housed in a TSSOP-14 package. It features an A-suffix grade with a typical input offset voltage of 1mV and a maximum of 4mV across the full temperature range. The device operates on a single supply from 2V to 36V or dual supplies of ±1V to ±18V. Key electrical parameters include a supply current of 0.9mA at 5V, low input bias current of 25nA, and a response time of 1.3µs.
Feature Summary
- Offers very low input offset voltage specification for precision applications
- Features wide power supply range compatible with single or split supplies
- Provides output voltage compatibility with TTL, MOS, and CMOS logic families
Applications
- Direct interface with TTL and CMOS logic circuits
- Precision voltage monitoring systems
- Threshold detection applications requiring low offset drift
Procurement Notes
Verify the specific ordering suffix matches the required package type and tape & reel quantity. Confirm RoHS compliance status and lead-free specifications against the latest manufacturer documentation before finalizing procurement orders.
Selection Notes
Select this component when high precision is required due to its low offset voltage characteristics. Ensure the application utilizes the open-collector output correctly with appropriate pull-up resistors. Verify that the operating temperature range aligns with system requirements.
Part Context
This part belongs to the LM2901/2903 series of dual and quad differential comparators. The 'A' designation indicates a tighter offset voltage tolerance compared to standard versions. The T14 suffix specifies the TSSOP-14 surface mount package configuration.
