Overview
The IS31AP4996-SLS2-TR is a monolithic Class-AB audio power amplifier in an MSOP-8 package. It delivers 1.1W continuous RMS output into an 8Ω load at 5V supply with 1% THD+N. The device operates from 2.7V to 5.5V and features an active-high standby mode reducing current to less than 2μA. Key electrical parameters include 0.074% distortion at 0.5W, 56dB PSRR at 217Hz, and near-zero click-and-pop performance.
Feature Summary
- Bridge-tied load (BTL) architecture for high efficiency
- Active-high standby mode for ultra-low power consumption
- Internal thermal shutdown protection
- Unity-gain stable configuration via external resistors
Applications
- Mobile phones
- Portable electronic devices
- Notebook computers
- PDAs
Procurement Notes
Verify the specific suffix 'SLS2' corresponds to the MSOP-8 lead-free package as defined in the ordering information table. Confirm that the reel quantity matches the specified 2500 units per reel. Ensure the industrial temperature range of -40°C to +85°C meets the operational requirements of the target application environment before finalizing procurement.
Selection Notes
Select this component for designs requiring a single-channel mono amplifier with minimal external components. The BTL configuration allows for higher output power compared to single-ended setups. Consider the wake-up time dependency on the bypass capacitor size when designing power sequencing. The active-high standby control offers flexibility for system-level power management strategies.
Part Context
This part belongs to the IS31AP4996 series of 1.1W audio power amplifiers manufactured by Lumissil Microsystems. The SLS2 suffix specifically denotes the MSOP-8 surface-mount package variant, distinct from the SOP-8 version identified by the GRLS2 suffix. Both variants share identical electrical characteristics and functional capabilities within the industrial temperature range.
Replacement Considerations
The IS31AP4996-GRLS2-TR serves as the direct pin-compatible alternative utilizing the SOP-8 package. Designers must verify land pattern compatibility when substituting between MSOP-8 and SOP-8 footprints. Electrical performance remains consistent across both package options.
