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.
