Overview
The LM2903QTH-13 is a dual differential voltage comparator from Diodes Incorporated, designed for automotive applications. It operates on a single supply of 2V to 36V or dual supplies of ±1V to ±18V. The device features very low supply current drain independent of voltage, with a typical value of 0.6mA at 5V. It includes low input bias current (25nA), low input offset current (±5nA), and a typical offset voltage of 2mV. Qualified to AEC-Q100 Grade 1, it supports an operating temperature range of -40°C to +125°C.
Feature Summary
- Qualified to AEC-Q100 Grade 1 standards for automotive compliance
- Low power supply current drain that remains independent of the magnitude of the power supply voltage
- Output voltage compatible with TTL, MOS, and CMOS logic families
- Differential input voltage range equal to the power supply voltage
Applications
- Motor control systems
- Instrumentation systems
- Switch-mode power supplies
- Industrial process control
Procurement Notes
Verify the specific package code TH corresponds to TSSOP-8 when sourcing. Confirm the -13 suffix indicates tape and reel packaging. Ensure the component meets AEC-Q100 Grade 1 requirements for your specific automotive application context. Check for RoHS 3 compliance status if required by your manufacturing regulations.
Selection Notes
Select this part for designs requiring automotive-grade reliability and wide voltage operation. The dual configuration suits applications needing two independent comparison functions in a compact TSSOP-8 footprint. Consider the low offset voltage specifications for precision sensing tasks where signal accuracy is critical across the full industrial temperature range.
Part Context
This component belongs to the LM2903Q series of dual comparators manufactured by Diodes Incorporated. It shares functional similarities with the LM2901Q quad comparator but offers a dual-channel architecture. The Q designation signifies automotive qualification, while the TH suffix identifies the TSSOP-8 surface-mount package variant within the broader product family.

FAQ
What is the maximum differential input voltage allowed?
The differential input voltage range is equal to the power supply voltage, allowing positive excursions to exceed VCC without damaging the device.
Is the common-mode input voltage range inclusive of ground?
Yes, the common-mode input voltage range includes ground, allowing operation with signals referenced to the negative supply rail.
