Voltage Divider Amps

Optimizing Resistor Dividers At A Comparator
At a very low resistance, however, amps of current are drawn through the divider, which is also unacceptable. ICs that use a resistive divider at a comparator input must have an accurate trip point design a voltage divider to meet a desired accuracy requirement. … Read More
