LMH7322SQE/NOPB

Overview

The LMH7322SQE/NOPB is a dual high-speed comparator manufactured by Texas Instruments, housed in a 24-WQFN (4x4 mm) package. It features RSPECL, LVDS, and differential outputs with a maximum propagation delay of 0.783 ns. The device operates on a single supply voltage ranging from 2.7 V to 12 V or dual supplies of ±1.35 V to ±6 V. Key electrical specifications include a typical output current of 25 mA, a maximum static current of 10 mA, and an input offset voltage of 8 mV at 5 V. It supports a maximum input bias current of 5 µA at 5 V and offers a typical CMRR/PSRR of 80 dB with 75 mV hysteresis.

Feature Summary

• Provides high-speed signal comparison with sub-nanosecond propagation delay for precise timing applications.
• Features versatile output drivers compatible with RSPECL, LVDS, and differential logic standards.
• Operates efficiently within a wide single or dual power supply range while maintaining low static current consumption.

Applications

• High-speed data acquisition systems requiring fast threshold detection
• Video signal processing circuits utilizing RSPECL interfaces
• Precision timing and pulse generation applications

Procurement Notes

Verify the specific suffix 'SQE' against official Texas Instruments documentation to confirm exact pinout, temperature grade, and packaging variations. Ensure compatibility with the 24-WQFN footprint and exposed pad thermal requirements during PCB layout. Confirm RoHS3 compliance status for environmental regulations.

Selection Notes

Select this component when sub-nanosecond response times are critical compared to standard comparators. Consider the RSPECL/LVDS output options if interfacing directly with high-speed digital receivers without additional translation stages. Evaluate the 24-WQFN package constraints for thermal management and board space availability.
