Overview
The AP331AWRG-7 is a single-channel precision analog comparator manufactured by Diodes Incorporated, housed in an SOT-25R-5 surface-mount package. It operates on a supply voltage range of 2V to 36V (single) or ±1V to ±18V (dual). Key electrical parameters include a maximum input offset voltage of 8mV, a typical response time of 1.3μs, and a low 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
- Features a wide supply voltage range supporting both single and dual power configurations.
- Provides high precision with low input offset voltage specifications for accurate signal comparison.
- Maintains extremely low supply current drain that remains independent of the supply voltage magnitude.
- Includes an open-collector output compatible with various digital logic families.
Applications
- Limit comparators
- Simple analog to digital converters
- Pulse, square wave and time delay generators
- Wide range VCO and MOS clock timers
Procurement Notes
Verify the specific ordering suffix 'WR' corresponds to the SOT-25R package variant when sourcing. Confirm RoHS compliance status as indicated in official documentation. Ensure the application environment stays within the specified operating temperature range of 0°C to +70°C. Check for any recent Product Change Notices regarding leadframe material updates that may affect long-term reliability.
Selection Notes
Select this component when a single-channel comparator with ground-referenced input capability is required. It is suitable for battery-operated applications due to its low power consumption. Consider the SOT-25R package for space-constrained PCB layouts. Verify that the open-collector output configuration aligns with the downstream logic interface requirements.
Part Context
This part belongs to the AP331A series of single differential comparators designed for general-purpose precision applications. The AP331AWG-7 represents the standard SOT-25 package version, while the WR suffix denotes the SOT-25R variant. Both share identical electrical characteristics but differ in physical footprint dimensions.

FAQ
Can the AP331AWRG-7 operate with inputs below ground?
No, the input common-mode voltage range includes ground but should not go negative by more than 0.3V to avoid forward biasing internal junctions.
Is bypass capacitance required across the power supply?
It is usually unnecessary to use a bypass capacitor across the power supply line for this device, though standard PC board layout helps reduce stray coupling.
