MAX9075/MAX9077 Low-Cost, Ultra-Small, 3µA Single-Supply Comparators General Description Features
The MAX9075/MAX9077 single/dual comparators are o
580ns Propagation Delay from Only 3µA
optimized for 3V and 5V single-supply applications. These comparators have a 580ns propagation delay and o
2.1V to 5.5V Single-Supply Operation
consume just 3µA per comparator. The combination of o
Ground-Sensing Inputs
low-power, single-supply operation down to 2.1V, and ultra-small footprint makes these devices ideal for all o
Rail-to-Rail Outputs
portable applications. o
No Output Phase Inversion for Overdriven Inputs
The MAX9075/MAX9077 have a common-mode input o
No Differential Clamp Across Inputs
voltage range of -0.2V to VCC - 1.2V. Unlike many com- parators, there is no differential clamp between the o
