TLV3801DSGR

Comparators Overview

The TLV3801DSGR is a single-channel high-speed analog comparator manufactured by Texas Instruments, housed in an 8-pin WSON package. It features Low-Voltage-Differential-Signal (LVDS) outputs and operates on a single supply voltage ranging from 2.7 V to 5.25 V. The device exhibits a typical propagation delay of 225 ps with low overdrive dispersion of 5 ps. It supports a toggle frequency up to 3 GHz and can detect narrow pulses as short as 240 ps. Key electrical characteristics include a maximum input offset voltage of ±0.5 mV, internal hysteresis of 2 mV, and a quiescent current of approximately 26.6 mA per channel.

Comparators Feature Summary

• Features LVDS complementary outputs designed to increase data throughput while optimizing power consumption and reducing electromagnetic interference.
• Provides split input and output ground references, allowing flexible operation with either single or split supply configurations.
• Capable of detecting narrow pulse widths down to 240 ps with minimal variation in propagation delay due to low overdrive dispersion.

Comparators Applications

• Distance sensing in LIDAR systems
• Time-of-Flight sensors for factory automation and drone vision
• High-speed trigger functions in oscilloscopes and logic analyzers
• High-speed differential line receivers

Comparators Procurement Notes

Verify the specific ordering suffix 'GR' corresponds to the reel packaging configuration required for your assembly process. Confirm that the component meets RoHS standards and humidity sensitivity classifications before integration. Ensure the design accommodates the thermal requirements associated with the WSON package and the specified operating temperature range.

Comparators Selection Notes

Select this component when applications demand sub-nanosecond response times and compatibility with standard LVDS interfaces such as FPGAs or CPUs. Consider the split supply architecture if the system requires independent referencing for input and output grounds. Evaluate the 2 mV internal hysteresis against noise levels; external feedback may be necessary for signals with slow rise times.

Comparators Part Context

This part belongs to the TLV380x family of high-speed comparators, which also includes the dual-channel TLV3802 and the zero-hysteresis TLV3811 variants. All members share similar performance metrics regarding propagation delay and toggle frequency but differ in channel count, package type, and internal hysteresis settings tailored for specific signal integrity needs.

Comparators Replacement Considerations

Direct functional substitutes within the same series include the TLV3802 for dual-channel requirements and the TLV3811 for applications requiring different hysteresis levels. Verify pinout compatibility and package dimensions when transitioning between these variants.
