3 Description

The TLV380x/TLV3811(C) 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 TLV380x/TLV3811(C) 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 TLV380x/TLV3811(C) 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 and TLV3802 are in an 8-pin WSON

and 12-pin WSON package, respectively, while the

TLV3811(C) is in a tiny 6-pin DSBGA package, which

makes them desirable for space sensitive applications

such as an optical sensor module.
