Overview
The IS31AP2111-ZLS1 is a digital I2S interface audio amplifier manufactured by Lumissil Microsystems. It delivers 20W stereo output into 8Ω loads or 40W mono into 4Ω loads from a 24V supply. The device integrates advanced audio processing including a 20-band speaker EQ, dynamic range control (DRC), and volume control. It operates via an I2C programmable interface and features Class-D efficiency without requiring external heat sinks.
Feature Summary
- Integrates 20-band parametric equalizer and dynamic range control for precise audio tuning
- Supports digital I2S input with full programmability via I2C control interface
- Class-D architecture provides high efficiency eliminating the need for external heat sinks
- Includes robust protection mechanisms against short circuits and over-temperature conditions
Applications
- Portable audio systems requiring high power density
- Home theater and surround sound setups
- Professional audio mixing equipment
- Active loudspeaker designs
Procurement Notes
Verify the specific suffix ZLS1 to confirm package type and reel configuration. Confirm current availability status as manufacturing lifecycles change. Ensure compatibility with existing I2C bus voltage levels in the target system design before finalizing procurement orders.
Selection Notes
Select this component when digital audio sources are available via I2S. Choose this model for applications requiring integrated DSP functions like EQ and DRC within a single amplifier stage. Verify that the 24V supply rail matches the system power budget requirements for optimal 20W performance.
Part Context
This part belongs to the IS31AP series of digital audio amplifiers from Lumissil Microsystems. It complements other models in the family by offering specific digital signal processing capabilities tailored for complex audio environments while maintaining compact form factors suitable for space-constrained electronic devices.
Replacement Considerations
Check datasheets for alternative ISSI/Lumissil models such as IS31AP2110 if analog inputs are preferred. Verify pinout compatibility with existing PCB layouts before substituting with other Class-D amplifiers from different manufacturers.
