Overview
The APX321WG-7 is a single-channel operational amplifier from Diodes Incorporated, manufactured in the APX321 series. It operates within a supply voltage range of 2.5V to 5.5V and supports an ambient temperature range of -40°C to +85°C. Key electrical parameters include a gain-bandwidth product of 1 MHz, a slew rate of 1 V/µs, and a typical supply current of 110 µA. The device features rail-to-rail input and output capabilities, with an input offset voltage typically at 7 mV and an input bias current of 10 nA.
Feature Summary
- Rail-to-rail input and output swing capability for low-voltage signal processing
- Low power consumption with optimized speed-to-power ratio
- Elimination of crossover distortion for improved signal integrity
Applications
- Active filters
- General purpose low voltage applications
- General purpose portable devices
Procurement Notes
Verify that the component matches the specific SOT25 package configuration and the -7 tape and reel packaging suffix. Confirm compliance with RoHS directives and ensure the green molding compound specification aligns with project requirements. Cross-reference the manufacturer part number against official datasheets to validate authenticity before integration.
Selection Notes
Select this component for designs requiring single-channel amplification with minimal space constraints due to the compact SOT25 footprint. It is suitable for battery-powered systems where low quiescent current is critical. Ensure the application does not exceed the absolute maximum ratings regarding differential input voltage or short-circuit conditions to maintain reliability.
Part Context
This part belongs to the APX321/APX358/APX324 family of low voltage, rail-to-rail operational amplifiers. While the APX358 offers dual channels and the APX324 provides quad channels, the APX321 is specifically configured as a single amplifier. All variants share similar electrical characteristics but differ in channel count and available package options.
Replacement Considerations
Direct substitutes within the same family include the APX321SEG-7, which utilizes the SOT353 package instead of SOT25. Other family members like the APX358 or APX324 offer additional channels but require different pin configurations and are not direct pin-compatible replacements for the single-channel APX321.
