Overview
The LA321AAAD is a general-purpose operational amplifier manufactured by Diodes Incorporated. It features a single circuit configuration housed in an SC-74A (SOT-753) surface-mount package. Key electrical specifications include a supply current of 150µA, an output current capability of 40 mA per channel, and a gain-bandwidth product of 1 MHz. The device operates with a supply voltage range from 2.5 V to 5.5 V and maintains a typical input offset voltage of 1.7 mV. It supports a slew rate of 1 V/µs and functions within a temperature range of -40°C to 125°C.
Feature Summary
- Single-channel general-purpose operational amplifier design
- Rail-to-rail output capability for maximum dynamic range
- Low power consumption suitable for battery-operated applications
- Extended operating temperature range for industrial environments
Applications
- Signal conditioning in portable electronic devices
- Active filtering in audio processing circuits
- Sensor interface amplification
- Voltage buffering in low-power systems
Procurement Notes
Verify the specific suffix 'AAAD' against the manufacturer's latest datasheet to confirm pinout and electrical characteristics, as suffixes often denote package or temperature variations. Confirm RoHS compliance status and check for any recent Product Change Notifications (PCNs) regarding leadframe material or bond wire composition updates before finalizing procurement plans.
Selection Notes
Select this component when a single-channel op-amp with rail-to-rail output is required in a compact SOT-753 package. It is suitable for designs needing moderate bandwidth (1 MHz) and drive capability (40 mA) with low quiescent current. Ensure the application voltage stays within the 2.5 V to 5.5 V range and that the thermal environment does not exceed the 125°C junction limit.
Part Context
The LA321 series belongs to Diodes Incorporated's portfolio of analog linear integrated circuits. This specific part is a standard operational amplifier variant designed for cost-sensitive and space-constrained applications. It shares functional similarities with other single-supply op-amps but is distinguished by its specific package type and electrical parameters optimized for consumer and industrial electronics.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source data. Consult the manufacturer's official cross-reference documentation or contact technical support for verified equivalents.
