Overview
The MAX9024AUD+ is a quad analog comparator from the MAX9021/MAX9022/MAX9024 family, designed for low-power single-supply applications. It operates within a supply voltage range of 2.5V to 5.5V (or ±1.25V to ±2.75V dual). Key electrical parameters include a typical propagation delay of 3µs and a supply current of 2.8µA per comparator. The device features internal hysteresis of 4mV, an input offset voltage of ±1mV (max ±8mV), and rail-to-rail output swing. It is housed in a 14-pin TSSOP package and supports an operating temperature range of -40°C to +125°C.
Feature Summary
- Low power consumption with 2.8µA supply current per comparator
- Internal 4mV hysteresis for noise immunity
- Rail-to-rail output swing capability
- No phase reversal for overdriven inputs
Applications
- Battery-powered portable systems
- Mobile communications
- Sensor-signal detection
- Photodiode preamps
- Threshold detectors/discriminators
Procurement Notes
Verify the specific suffix 'AUD' corresponds to the 14-pin TSSOP package variant when sourcing. Confirm RoHS compliance status via the '+' designation in the part number. Ensure the supplier provides the official Analog Devices datasheet for accurate pinout and electrical characteristic validation before integration into designs.
Selection Notes
Select this component for designs requiring multiple comparators in a small footprint with minimal power draw. The quad configuration reduces board space compared to using individual single or dual units. Consider the 3µs propagation delay for timing-critical paths; faster alternatives may be needed for high-speed data recovery applications.
Part Context
The MAX9024AUD+ belongs to the MAX902x series of micropower comparators. This family includes single (MAX9021), dual (MAX9022), and quad (MAX9024) variants. The 'AUD' suffix specifically denotes the 14-pin TSSOP package option, distinguishing it from SOIC or other package types within the same electrical family.
Replacement Considerations
Direct substitutes within the same family include MAX9024ASD+ (SOIC-14 package). Other compatible options may exist within the broader Maxim Integrated comparator portfolio, but pin compatibility and package dimensions must be verified against the TSSOP-14 form factor.
