This datasheet introduces the MAX9075/MAX9077 single/dual comparators, which are optimized for 3V and 5V single-supply applications. These comparators have a 580ns propagation delay and consume just 3µA per comparator. The combination of low-power, single-supply operation down to 2.1V, and ultra-small footprint makes these devices ideal for all portable applications.
The MAX9075 (single comparator) and MAX9077 (dual comparator) are optimized for 2.1 V to 5.5 V single‑supply operation. Their ultra‑small SC70, SOT23, UMAX and SO packages make them suitable for battery‑powered systems, keyless entry, IR receivers and other portable applications. They feature rail‑to‑rail inputs, no differential clamp, and can drive up to 2 mA loads.
Electrical characteristics include a typical 580 ns propagation delay, 3 µA supply current per comparator, input offset voltage of ±1 mV to ±8 mV, and a common‑mode range of –0.2 V to VCC‑1.2 V. The datasheet provides detailed pin configurations, absolute maximum ratings, and typical operating curves for supply current, propagation delay, and hysteresis design.
| Supply Current per Comparator | 3 µA |
|---|---|
| Input Offset Voltage | ±1 to ±8 mV |
| Common‑Mode Input Voltage Range | -0.2 V to VCC‑1.2 V |
| Output Load Capability | 2 mA |
| Operating Supply Voltage Range | 2.1 V to 5.5 V |
They operate from 2.1 V up to 5.5 V on a single supply.
Each comparator consumes about 3 µA of supply current.
The MAX9075 is offered in 5‑pin SC70 and SOT23 packages; the MAX9077 is available in 8‑pin SOT23, UMAX, and SO packages.
