Overview
The MAX40070ANA16+T is a single micropower comparator from Analog Devices, designed for battery-operated devices with tight space and power constraints. It features a rail-to-rail input voltage range of 0V to +27.5V on the IP pin, independent of supply voltage. The device consumes only 16µA typical supply current with a propagation delay of 2µs. It includes an internal high-precision 1.6V reference and a current source for customized thresholds. Operating over -40°C to +125°C, it offers an open-drain output in an 8-bump WLP package.
Feature Summary
- Rail-to-rail input voltage range extending up to 27.5V independent of supply voltage
- Internal high-precision voltage reference and current source for threshold customization
- Open-drain output stage capable of sharing a single pull-up resistor
- Internal hysteresis to ensure clean switching and prevent oscillation
Applications
- Notebook and tablet computers
- Portable medical devices
- Industrial equipment
- IoT applications
Procurement Notes
Verify the specific suffix 'ANA16+' corresponds to the 8-bump WLP package configuration as listed in the ordering information. Confirm RoHS compliance status indicated by the '+' symbol. Ensure the tape and reel packaging designation matches system requirements. Cross-reference the part number against the latest manufacturer documentation to confirm availability and any potential future product status changes.
Selection Notes
Select this component when board space is limited and low power consumption is critical. The wide common-mode input range allows direct interfacing with high-voltage signals without external dividers. The internal reference simplifies design by reducing external component count. Consider the open-drain output capability if wired-OR logic or level shifting beyond VDD is required.
Part Context
This part belongs to the MAX40070/MAX40072 family of high-voltage, low-power comparators. The MAX40070 variant provides a single channel, while the MAX40072 offers dual channels. Both share similar electrical characteristics but differ in package options and channel count. This family targets applications requiring precision in constrained environments.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation.
