Overview
The NCA-ONA10IVUCX is a digital input, mono Class-D audio amplifier with integrated speaker voltage and current sensing. It operates from a PVDD supply of 5.5 V to 14 V and a DVDD supply of 1.62 V to 1.98 V. The device delivers up to 16 W into a 4 Ω load at 14 V supply with 1% THD+N. It supports I2S, TDM, and PDM digital audio interfaces with sampling rates from 16 kHz to 96 kHz. The package is a 30-bump WLCSP measuring 2.31 mm x 2.89 mm.
Feature Summary
- Filter-less mono Class-D amplifier architecture capable of direct battery connection without boost capacitors.
- Integrated real-time speaker voltage and current sensing with data transmission via digital output.
- Fast automatic gain control for brownout protection reacting within microseconds.
- Multi-speaker synchronization capability using a dedicated MAGC bus.
Applications
- Laptops
- Smart speakers
- Portable speakers
- IoT devices
Procurement Notes
Verify the complete part number NCA-ONA10IVUCX against official onsemi documentation to ensure correct suffix identification. Confirm that the WLCSP30 package and tape & reel shipping format match project requirements. Cross-reference electrical specifications with the latest datasheet revision to account for any parameter updates.
Selection Notes
Select this component for applications requiring high-efficiency digital audio amplification with built-in diagnostic capabilities. Ensure the host system supports the required digital audio formats (I2S, TDM, or PDM) and provides appropriate power rails. Consider the thermal performance and board layout constraints associated with the small WLCSP package when designing the PCB.
Part Context
This device belongs to the ONA10IV family of digital audio amplifiers manufactured by onsemi. It is designed as an endpoint solution that combines amplification with speaker monitoring functions. The product line targets portable electronics where space efficiency and audio quality are critical priorities.
Replacement Considerations
Direct substitutes are not explicitly listed in the provided documentation. Verify compatibility with existing designs by comparing pin configurations, electrical characteristics, and interface protocols with alternative Class-D amplifiers offering similar power output and sensing features.
FAQ
What digital audio formats does the NCA-ONA10IVUCX support?
The device supports Pulse Code Modulation (PCM) formats including I2S, Left Justified, and Time Division Multiplexing (TDM), as well as Pulse Density Modulation (PDM).
How does the device handle brownout events?
It features a fast automatic gain control (AGC) that reacts within microseconds to reduce gain during voltage drops, protecting the speaker and maintaining audio integrity.
Can multiple ONA10IV devices be synchronized?
Yes, up to eight devices can share digital audio interfaces and use a dedicated MAGC bus to synchronize gain adjustments across multiple instantiations.
