3 Description
The TLV3801-Q1 is a 225-ps high speed comparator
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-Q1 has 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-Q1 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-Q1 is in an 8-pin WSON package which
makes it desirable for space sensitive applications
such as an optical sensor module.
