ANALOG DEVICES MAX44269EWL+T Analogue Comparator, General Purpose, 2 Channels, 1.8V to 5.5V, WLP, 9 Pins

The MAX44269EWL+T is a low-power dual comparator in 9 pin WLP package. The MAX44269 is an ultra-small and low-power dual comparator ideal for battery-powered applications such as cell phones, notebooks and portable medical devices that have extremely aggressive board space and power constraints. The IC can be powered from supply rails as low as 1.8V and up to 5.5V. It requires just 0.5?A of typical supply current per comparator. It has a rail-to-rail input structure and a unique output stage that limits supply current surges while switching. This design also minimizes overall power consumption under dynamic conditions. The IC has open-drain outputs, making it suitable for mixed voltage systems. The IC also features internal filtering to provide high RF immunity. It operates over a -40°C to +85°C temperature.

• Ultra low power consumption 0.5?A per comparator
• Guaranteed operation down to VCC = 1.8V
• Input common-mode voltage range extends 200mV beyond-the-rails
• 6V tolerant inputs independent of supply
• Open drain outputs
• Internal filters enhance RF immunity
• Crowbar current free switching
• Internal hysteresis for clean switching
• No output phase reversal for overdriven inputs
