8.2.1 High Voltage Precision Comparator

Many different systems require controlled voltages across numerous system nodes to ensure robust operation. A comparator can be used to monitor and control voltages by comparing a reference threshold voltage with an input voltage and providing an output when the input crosses this threshold.

The TLV935x family of op amps make excellent high voltage comparators due to their MUX-friendly input stage (see the Input Protection Circuitry section). Previous generation high-voltage op amps often use back-to-back diodes across the inputs to prevent damage to the op amp which greatly limits these op amps to be used as comparators, but the TLV935x's patented input stage allows the device to have a wide differential voltage between the inputs.
