Overview
The MAX9032AUA-T is a dual analog comparator from the MAX9030/MAX9031/MAX9032/MAX9034 family, optimized for single-supply applications ranging from +2.5V to +5.5V. It features a propagation delay of 188ns and consumes 35µA of supply current per comparator over an operating temperature range of -40°C to +125°C. The device includes 4mV of built-in hysteresis for noise immunity and prevents oscillations with slow-moving input signals. Its common-mode input voltage extends from the negative supply to within 1.1V of the positive supply. The output stage reduces switching current during transitions to minimize power-supply glitches.
Feature Summary
- Rail-to-rail comparator output swings
- Internal 4mV comparator hysteresis
- No phase reversal for overdriven inputs
Applications
- Battery-Powered Systems
- Portable Systems
- Mobile Communications
- Sensor Signal Detection
- Photodiode Preamps
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status by checking the specific ordering suffix against official documentation. Ensure storage conditions adhere to specified limits to maintain reliability. Validate package integrity upon receipt to prevent damage to the ultra-small footprint components.
Selection Notes
Select this part when low-power consumption and small physical size are critical constraints. The dual configuration suits designs requiring two independent comparison functions without shutdown capability. Verify that the required supply voltage falls within the +2.5V to +5.5V range. Consider the 188ns propagation delay relative to system timing requirements.
Part Context
This component belongs to the MAX903x series of low-cost, ultra-small, single/dual/quad single-supply comparators manufactured by Analog Devices / Maxim Integrated. The series includes single (MAX9030/MAX9031), dual (MAX9032), and quad (MAX9034) variants. The MAX9032 specifically provides two comparators in an 8-pin µMAX package, offering a compact solution for space-constrained portable electronics.
Replacement Considerations
The MAX9032AUA+ serves as the lead-free/RoHS-compliant equivalent of the MAX9032AUA variant. Verify pin compatibility and electrical specifications before substituting other dual comparators from different manufacturers.
