Overview
The MAX9032ASA+ is a dual-channel analog comparator 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 channel across the -40°C to +125°C operating temperature range. The device incorporates 4mV of built-in hysteresis to ensure noise immunity and prevent oscillations during slow-moving input signals. Its input common-mode voltage extends from the negative supply to within 1.1V of the positive supply, while the push-pull output stage swings rail-to-rail.
Feature Summary
- Dual-channel configuration without shutdown functionality
- Rail-to-rail output swing with reduced switching current to minimize power-supply glitches
- Internal 4mV hysteresis for enhanced noise immunity
- No phase reversal for overdriven inputs
Applications
- Battery-powered portable systems
- Mobile communications devices
- Sensor signal detection circuits
- Photodiode preamplifiers
- Threshold detectors and discriminators
Procurement Notes
Verify that the ordering suffix 'ASA+' corresponds specifically to the SOIC-8 package variant. Confirm RoHS compliance status associated with the '+' designation. Ensure the component meets the required -40°C to +125°C industrial temperature grade specifications before integration into final designs.
Selection Notes
Select this part when a dual-channel comparator is required in an 8-pin surface-mount package. It is suitable for space-constrained designs needing low power consumption. Note that unlike the MAX9030, this specific model lacks a shutdown pin, making it permanently active during operation.
Part Context
This component belongs to the MAX903x family of ultra-small, low-cost comparators manufactured by Analog Devices/Maxim Integrated. The family includes single (MAX9030/MAX9031), dual (MAX9032), and quad (MAX9034) variants. The MAX9032ASA+ specifically utilizes the 8-pin SO package format.
Replacement Considerations
The MAX9032AUA+ serves as a direct functional substitute utilizing the µMAX-8 package instead of the SO-8 footprint.
