Window Comparator With Independent Adjustments (HA2841, HA4905) Window Comparator With Independent Adjust- ments (HA2841, HA4905) Application Note April 1998 AN9802 Introduction Window comparators, or limit comparators as they are There might be a temptation to change the comparator to an sometimes called, determine when the input voltage is within op amp. This is poor practice for any circuit which requires a pre-selected range. The output voltage usually goes to a high speed performance because the op amp output would TTL high when the input voltage is within the pre-selected saturate causing uncontroll……
