3 Description

The TLV3801/TLV3811 are 225-ps high speed

comparators with a wide power supply range and a

very high toggle frequency of 3 GHz. Along with an

operating supply voltage range of 2.7 V to 5.25 V for

single supply and 2.7 V to 5.25 V for split supply,

all of these features come in industry-standard small

packages, making these devices an excellent choice

for LIDAR, differential line receiver applications, and

test and measurement systems.

The TLV3801/TLV3811 have a very strong input

overdrive performance of 5 ps, and narrow pulse

width capabilities of just 240 ps. This combination

of low variation in propagation delay due to input

overdrive and the ability to detect narrow pulses make

these devices excellent choices for Time-of-Flight

(ToF) applications such as in factory automation and

drone vision.

The Low-Voltage-Differential-Signal (LVDS) output of

the TLV3801/TLV3811 helps increase data throughput

and optimizes power consumption. Likewise, the

complementary outputs help to reduce EMI by

suppressing common mode noise on each output.

The LVDS output is designed to drive and interface

directly with other devices that accept a standard

LVDS input, such as most FPGAs and CPUs

downstream in an application.

The TLV3801 is in an 8-pin WSON package while

the TLV3811 is in a tiny 6-pin WCSP package, which

makes them desirable for space sensitive applications

such as an optical sensor module.
