描述 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 4.2 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 it desirable for space sensitive applications such as an optical sensor module.
