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.
