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.
