Description

The TS86x device (single, dual and quad) is

a rail-to-rail comparator characterized for 2.7 to

10 V operation over -40 °C to +85 °C temperature

ranges. It exhibits an excellent speed-to-power

ratio, featuring a current consumption of 6 μA per

comparator and a response time of 500 ns

at 2.7 V for a 100 mV overdrive.

Due to its ultra low power consumption and its

availability in a tiny package, the TS86x

comparator family is perfectly suited to battery-

powered systems. The output stage is designed

with a push-pull structure allowing a direct

connection to the microcontroller without

additional pull-up resistors.
