Overview
The LM2903ATH-13 is a dual differential voltage comparator manufactured by Diodes Incorporated, housed in an 8-pin TSSOP package. It operates from a single supply of 2V to 36V or split supplies of ±1V to ±18V. The device features very low supply current drain independent of voltage, with a typical consumption of 0.6mA at 5V. It offers low input bias current (25nA), low input offset current (±5nA), and a typical offset voltage of 1mV for the 'A' grade. The output saturation voltage is typically 200mV at 4mA sink current.
Feature Summary
- Low input offset voltage specification for precision applications
- Very low supply current drain that remains independent of power supply voltage magnitude
- Output voltage compatible with TTL, MOS, and CMOS logic families
- Differential input voltage range equal to the full power supply voltage
Applications
- Motor control systems
- Instrumentation systems
- Switch-mode power supplies
- Industrial process control
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 procurement. Ensure the component grade aligns with design requirements for offset voltage and temperature stability.
Selection Notes
Select this component when low quiescent current is critical across varying supply voltages. The 'A' suffix indicates tighter offset voltage tolerances compared to standard versions. Verify that the TSSOP-8 package dimensions fit the PCB layout constraints and that the open-collector output configuration suits the system's pull-up requirements.
Part Context
This part belongs to the LM2901/2903 series of dual and quad differential comparators. The series is designed for wide voltage range operation and direct interfacing with various logic families. The LM2903 variant specifically provides two independent comparators per package, distinguishing it from the four-channel LM2901.

FAQ
What is the maximum differential input voltage allowed?
The differential input voltage range is equal to the power supply voltage, allowing inputs to exceed VCC without damage as long as other voltages remain within the common mode range.
How does the 'A' suffix affect performance?
The 'A' suffix denotes a device with a typical input offset voltage of 1mV, which is half the typical offset voltage of the non-A device (2mV).
