TLV3811CYBGR

Comparators Overview

The TLV3811CYBGR is a single-channel high-speed analog comparator manufactured by Texas Instruments, featuring Low-Voltage Differential Signaling (LVDS) outputs. It operates on a single supply voltage ranging from 2.7 V to 5.25 V and delivers a typical propagation delay of 225 ps with an overdrive dispersion of 5 ps. The device supports a toggle frequency up to 3 GHz (6 Gbps) and can detect narrow pulses as short as 240 ps. Key electrical characteristics include a low input offset voltage of ±0.5 mV and zero internal hysteresis. It is housed in a compact 6-pin DSBGA package measuring 1.218 mm × 0.818 mm.

Comparators Feature Summary

• Features LVDS complementary outputs designed to increase data throughput and reduce electromagnetic interference.
• Provides ultra-fast response capabilities with 225 ps propagation delay for precise timing applications.
• Capable of detecting narrow input pulses down to 240 ps width.
• Includes split power rail architecture allowing independent input and output ground references.

Comparators Applications

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

Comparators Procurement Notes

Verify the specific 'C' suffix indicates zero internal hysteresis compared to standard variants. Confirm the DSBGA-6 package footprint matches the PCB layout requirements. Ensure the design accounts for the single-supply operation constraints defined in the datasheet. Validate that the 2.7 V minimum supply voltage aligns with the system power rails.

Comparators Selection Notes

Select this component when zero internal hysteresis is required for maximum sensitivity to small signal transitions. Choose the TLV3811CYBGR over the TLV3811 if noise immunity from internal hysteresis is not needed. Consider the 6-pin DSBGA package for space-constrained designs requiring a small body size. Evaluate the 225 ps propagation delay against system timing budgets.

Comparators Part Context

This part belongs to the TLV380x/TLV3811(C) family of high-speed comparators. While the TLV3801 and TLV3802 utilize WSON packages and support split supplies, the TLV3811(C) series utilizes a 6-pin DSBGA package and operates on a single supply. The 'C' variant specifically distinguishes itself by having 0 mV of internal hysteresis, unlike the TLV3811 which includes 1.1 mV.

Comparators Replacement Considerations

The TLV3811YBGR serves as a direct substitute within the same family but includes 1.1 mV of internal hysteresis instead of 0 mV. Verify if the presence of internal hysteresis affects the specific application's signal integrity requirements before swapping.
