Comparators datasheet and documents for MAX989EUA
Comparators Overview
The MAX989EUA is a dual micropower comparator from the MAX985/986/989 series, manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single supply voltage ranging from 2.5V to 5.5V or dual supplies of ±1.25V to ±2.75V. The device features rail-to-rail inputs and outputs with a propagation delay of 300ns. It consumes 11µA of quiescent supply current and has an input bias current of typically 1.0pA. The output stage is push-pull, capable of sinking and sourcing up to 8mA. It is housed in an 8-pin SOT-23 package.
Comparators Feature Summary
- Micropower operation with 11µA quiescent supply current
- Rail-to-rail input and output capability
- Push-pull output stage for direct drive loads
- Internal hysteresis for clean switching
Comparators Applications
- Battery-powered systems
- Level translation
- Threshold detection circuits
Comparators Procurement Notes
Verify the specific suffix 'EUA' against official datasheets to confirm the package type (SOT-23) and temperature range. Confirm availability status as distribution data may vary. Ensure compatibility with system voltage requirements between 2.5V and 5.5V before integration.
Comparators Selection Notes
Select this component for applications requiring low power consumption and fast response times in compact designs. The push-pull output eliminates the need for external pull-up resistors. Consider the 300ns propagation delay for timing-critical signals. Verify that the 8mA output drive current meets load requirements.
Comparators Part Context
Part of the MAX985/986/989 family of micropower comparators designed for low-voltage portable electronics. These devices offer high performance in small packages, making them suitable for space-constrained mobile and handheld applications where power efficiency is critical.
Comparators FAQ
What is the typical input offset voltage?
The typical input offset voltage is 0.5mV.
Can the open-drain versions handle voltages beyond VCC?
Yes, the open-drain variants (MAX986/990/994) can be pulled beyond VCC to 6V max above VEE, but the MAX989EUA has a push-pull output.
