The base product number LM2901 is a widely second-sourced industry standard, and the 'AV' suffix denotes the extended industrial temperature range. Single-supply operation from 2 V to 32 V (or split supplies ±1 V to ±16 V) means this comparator runs on a 5 V ADC supply or an industrial bus without a secondary regulator. Maximum input offset voltage of 2 mV at 32 V supply keeps the switching threshold accurate. ## Output type flexibility — open-collector wired-OR and level translation The open-collector output (also listed as CMOS, MOS, and TTL-compatible) lets multiple comparator outputs be tied together in a wired-OR configuration for window comparators or fault-summary flags. The pull-up resistor can connect to a different supply than the comparator itself, enabling 5 V logic to drive a 3.3 V microcontroller input or a 24 V PLC input module without a level shifter.","metaTitle":"LM2901AVQDRG4 Quad Differential Comparator, -40°C to 125°C","metaDescription":"Texas Instruments LM2901AVQDRG4 quad differential comparator. 2V to 32V supply, open-collector output, industrial temp range.

In practice the output stage is an open-collector NPN transistor that can be pulled up to any voltage within the supply range, making it compatible with all those logic families."},{"question":"Is LM2901AVQDRG4 compatible with 5V logic?","answer":"Yes. The open-collector output can be pulled up to 5 V via a resistor, and the inputs accept signals up to the positive supply rail. The input bias current is a maximum 0.25 µA at 5 V, so the comparator does not load the 5 V logic output."},{"question":"What is the difference between LM2901AVQDRG4 and LM2901DR?","answer":"The primary difference is the temperature grade. Both are quad comparators in 14-SOIC with the same pinout and supply range. For designs that see under-hood or outdoor ambient temperatures above 85°C, the 'AV' suffix variant is the correct choice."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM2901AVQDRG4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM2901AVQDRG4 when reusing this data.
