Page 2: Introduction
The TLV3602EVM is an evaluation board designed to evaluate the high-speed TLV3602 comparator. The TLV3602EVM has layout options intended to make it simple to evaluate timing performance with different measurement tools. The output of the TLV3602 allows for direct connection to a 50 Ω terminated oscilloscope. -

Page 8: Board Setup
5 Board Setup 5.1 Supply Voltage The TLV3602EVM operates using a V (Supply Voltage, or VCC - VEE) from 2.4 V to 5.5 V. Connect VCC to TP1, VEE to TP2, and GND to either TP3 or TP4. If using single supply configuration, connect system ground to GND and VEE. -
Page 9: Outputs
Figure 5-4. Output Side Block Diagram 5.4 Hysteresis The TLV3602EVM is able to support external hysteresis for each TLV3602 non-inverting input. When configuring the EVM for hysteresis, the non-inverting input signal should now be connected to the INA+SENSE SMA connector. The reason for this is hysteresis requires both a series input resistor and a feedback resistor from output to input. -
