LHC2031中文资料Micropower, Single-Supply, WLCSP Comparator + PrecisionReference Ics数据手册Legendsemi规格书

描述 Description

The LHC2031 combinations of low-power comparators and precision voltage references. Their operating voltage range makes them ideal for both 3V and 5V systems. The LHC2031 have a single comparator and reference consuming only 40μA of supply current. Low-voltage operation and low supply current make these devices ideal for battery-operated systems.

The comparators feature rail-to-rail inputs and outputs, with a common-mode input voltage range that extends 250mV beyond the supply rails. Input bias current is typically 1.0pA, and input offset voltage is typically 0.5mV. Internal hysteresis ensures clean output switching, even with slow-moving input signals. The output stage features a unique design that limits supply current surges while switching, virtually eliminating supply glitches typical of many other comparators. This design also minimizes overall power consumption under dynamic conditions. The comparator outputs have rail-to-rail,push-pull output stages. The propagation delay is200ns, even with the low-operating supply current.

The reference output voltage is set to 1.23V. Theinitial accuracy is around ±0.4% and 100ppm/°C maxtempco. The voltage references can sink or sourceup to 500μA of load current.
