Procurement Notes
Verify component status as the AS3400 is listed as obsolete in distributor records. Confirm availability through authorized channels or alternative sources if current production is required. Check datasheet revisions for any design changes prior to integration.
Selection Notes
Select this component for designs requiring a compact, low-voltage Class AB amplifier with digital control features. Ensure the application environment stays within the specified -20°C to 85°C temperature range. Verify that the 1V to 1.8V supply constraint aligns with the system power architecture.
Part Context
The AS3400 belongs to the audio amplifier category within ams-OSRAM's standard product portfolio. It is designed for high-efficiency audio applications where space and power consumption are critical constraints. The device complements other audio solutions by offering integrated digital control and protection features in a small form factor.
Replacement Considerations
No verified public substitute part numbers are available for the AS3400. Designers should consult manufacturer documentation for potential obsolescence management strategies or contact sales for recommended alternatives.
