8-channel 8-bit voltage comparator

Overview

028TSMC_COMP_01 is a comparator that compares a reference voltage to an analog input voltage and contains 8 input channels with a programmable threshold, implemented using 8-bit digital-to-analog converter (DAC).
Conversion time is 25ns in worst case.
The block consists of input multiplexer 8:1, 8-bit DAC and 1-channel comparator.
The Comparator operates from analog VDDIO 3.3V/5.0V, VDD33 3.3V and digital voltage VDD09 0.9V. Bias currents should be delivered from an external source.
