Overview
The TWL6040A3SRSZQZQ is an 8-channel low-power audio codec designed for portable applications. It features four DACs and two ADCs, supporting up to 104-dB dynamic range. The device includes stereo capless headphone drivers, stereo speaker drivers with 1.5 W per channel capability, and differential earpiece drivers. Integrated power supplies consist of a negative charge pump and two LDOs for high PSRR. It operates from a battery voltage of 2.3 V to 5.5 V, with analog supply at 2.1 V and digital I/O at 1.8 V. The component utilizes a 6-mm × 6-mm 120-pin PBGA package.
Feature Summary
- Dual Phase-Locked Loops (PLLs) provide flexible clock support for various system frequencies.
- Integrated accessory plug/unplug detection and button press detection minimize sleep mode current consumption.
- Two vibrator and haptics feedback channels utilize differential H-bridge drivers for fast motor acceleration.
Applications
- Mobile and smart phones
- Handheld devices
- MP3 players
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to confirm exact packaging and environmental compliance details. Confirm availability status as the TWL6040 series may be designated as not recommended for new designs in some variants. Ensure compatibility with the intended host processor interface before finalizing procurement.
Selection Notes
Select this component when designing portable audio systems requiring integrated power management alongside high-quality audio conversion. The inclusion of capless headphone drivers and filterless speaker outputs reduces external component count. Verify that the host processor supports the required PDM interface and I2C control protocols for proper system integration.
Part Context
The TWL6040 is part of the Texas Instruments TWL60xx family of power management and audio codecs. It is specifically engineered for OMAP4-based systems, providing optimized power consumption and performance partitioning. The device integrates multiple audio inputs and outputs along with microphone biases and accessory detection functions into a single compact package.
Replacement Considerations
Check the TI Packaging Addendum for alternative orderable devices within the TWL6040 family, such as TWL6040A3ZQZR. Verify if other members of the TWL60xx series offer compatible pinouts or functional equivalents for existing designs.
FAQ
What is the maximum output power for the stereo speaker drivers?
The stereo speaker drivers have a 1.5-W capability per channel.
How does the device support low-power audio playback?
It supports a low-power mode operating from a 32-kHz sleep clock, enabling extended playback time.
What type of interface connects the TWL6040 to the host processor?
The device connects via a proprietary PDM interface for audio data communication.
