MAX9024ASD+T

Overview

The MAX9024ASD+T is a quad comparator from the MAX9021/MAX9022/MAX9024 family, 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 a typical propagation delay of 3μs and consumes 2.8μA of supply current per comparator across the -40°C to +125°C temperature range. It includes 4mV of internal hysteresis for noise immunity and offers rail-to-rail output swing without phase reversal for overdriven inputs. The component is housed in a 14-pin SO package.

Feature Summary

• Micropower 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
• Digital line receivers

Procurement Notes

Verify the specific ordering suffix ASD+T against the manufacturer's official documentation to confirm the 14-pin SO package and lead-free/RoHS-compliant status. Ensure compatibility with the required operating temperature range of -40°C to +125°C. Cross-reference the part number with the latest datasheet revision to confirm electrical characteristics and pin configurations match design requirements before procurement.

Selection Notes

Select this component when a low-power, space-saving quad comparator is needed for single-supply applications. It is suitable for designs requiring minimal quiescent current and built-in hysteresis to prevent oscillations with slow-moving signals. Consider the 14-pin SO package constraints and verify that the 3μs propagation delay meets the system timing requirements.

Part Context

The MAX9024ASD+T belongs to the MAX902x series of micropower comparators, which also includes single (MAX9021) and dual (MAX9022) variants. This series is optimized for low-power consumption while maintaining fast output response times. The MAX9024 specifically provides four independent comparators in a compact footprint, making it ideal for dense circuit board layouts in portable electronics.

Replacement Considerations

Direct substitutes within the same family include MAX9024AUD+T (14-pin TSSOP package). Verify package dimensions and pinout compatibility when considering alternative packages.
