AP331AWG-7

Overview

The AP331AWG-7 is a single differential comparator from Diodes Incorporated, housed in an SOT25 surface-mount package. It operates on a supply voltage range of 2V to 36V or ±1V to ±18V dual supplies. Key electrical parameters include a maximum input offset voltage of 8mV, typical response time of 1.3μs, and supply current drain of 0.4mA at 5V. The device features an open collector output capable of sinking up to 16mA and is compatible with TTL, DTL, ECL, MOS, and CMOS logic systems.

Feature Summary

• Low power supply current drain independent of supply voltage magnitude
• Input common-mode voltage range includes ground for single-supply operation
• Output voltage compatible with various logic families including TTL and CMOS
• Differential input voltage range equal to the power supply voltage

Applications

• Limit comparators
• Simple analog to digital converters
• Pulse, square wave and time delay generators
• Wide range VCO and MOS clock timers
• Multivibrators and high voltage digital logic gates

Procurement Notes

Verify the specific ordering suffix matches the required package type, as 'W' denotes SOT25 while 'WR' indicates SOT25R. Confirm RoHS compliance status and lead-free finish requirements against project specifications. Ensure environmental documentation aligns with regional regulations such as REACH. Cross-reference the manufacturer part number with distributor catalogs to validate authenticity and revision levels before finalizing procurement orders.

Selection Notes

Select this component when low power consumption is critical for battery-operated applications requiring wide voltage flexibility. The inclusion of ground in the common-mode input range simplifies circuit design for single-supply systems. Consider the open-collector output configuration for interfacing with different logic voltage levels. Evaluate thermal resistance characteristics if operating near maximum ambient temperature limits within the specified range.

Part Context

This device belongs to the AP331A series of precision voltage comparators designed by Diodes Incorporated. It is engineered specifically for operation over a wide range of single power supply voltages while maintaining low offset voltage specifications. The series supports both single and split power supply configurations, offering versatility in analog signal processing applications where precise threshold detection is required.

Replacement Considerations

AP331AWRG-7 serves as a direct functional substitute utilizing the SOT25R package variant instead of the standard SOT25.
