MAX991EUA+ General Description
The MAX991EUA+ is a versatile micropower comparator that offers low-voltage operation and rail-to-rail inputs and outputs. It is designed to operate effectively within a voltage range of +2.5V to +5.5V, making it suitable for various 3V and 5V systems. Additionally, it can also function with dual supplies of ±1.25V to ±2.75V. With a low power consumption of only 48µA per comparator, the MAX991EUA+ delivers efficient performance with a fast 120ns propagation delay
Features
- 120ns Propagation Delay
- 48µA Quiescent Supply Current
- +2.5V to +5.5V Single-Supply Operation
- Common-Mode Input Voltage Range Extends 250mV Beyond the Rails
- Push-Pull Output Stage Sinks and Sources 8mA Current (MAX987/MAX991/MAX995)
- Open-Drain Output Voltage Extends Beyond VCC (MAX988/MAX992/MAX996)
- Unique Output Stage Reduces Output Switching Current, Minimizing Overall Power Consumption
- 100µA Supply Current at 1MHz Switching Frequency
- No Phase Reversal for Overdriven Inputs
- Available in Space-Saving Packages:
- 5-Pin SC70 (MAX987/MAX988)
- 8-Pin µMAX (MAX991/MAX992)
