Dual Polarity High-Voltage Differential Input Interface for Low-Voltage Comparators Reference Design

Description

This TI Verified Design provides the theory: component selection: simulation: schematic: PCB layout: BOM: and measured performance for a dual polarity (bipolar): high-voltage differential input interface for low-voltage comparators. The design allows a comparator such as the TLV3201 to operate with a single +3.3 V supply and to compare two input voltages that not only exceed its normal input range: but can be of either (±) polarity. The design takes into account all the comparator and passive component errors and results in
