The MAX965–MAX970 single/dual/quad micropower comparators feature rail-to-rail inputs and outputs, and fully specified single-supply operation down to +1.6V. These devices draw less than 5µA per comparator and have open-drain outputs that can be pulled beyond VCC to 6V (max) above ground. In addition, their rail-to-rail input common-mode voltage range makes these comparators suitable for ultra-low-voltage operation. A +1.6V to +5.5V single-supply operating voltage range makes the MAX965 family of comparators ideal for 2-cell battery-powered applications. The MAX965/MAX967/ MAX968/MAX969 offer programmable hysteresis and an internal 1.235V ±1.5% reference. All devices are available in either space-saving 8-pin µMAX® or 16-pin QSOP packages.
The MAX965–MAX970 family are single, dual, and quad micropower comparators that operate from a single +1.6 V to +5.5 V supply. They feature rail‑to‑rail inputs and outputs, an internal 1.235 V reference, and programmable hysteresis, making them suitable for battery‑powered and low‑voltage applications.
