TWL6040A3ZBHR

Overview

The TWL6040A3ZBHR is an 8-channel low-power audio codec designed for portable applications. It features four DAC channels and two ADC channels, supporting stereo capless headphone drivers with up to 104-dB dynamic range and stereo 8-ohm, 1.5-W per channel speaker drivers. The device includes integrated power supplies such as a negative charge pump and two LDOs, along with accessory plug detection and thermal protection. It operates on 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 is housed in a 6-mm × 6-mm 120-pin NFBGA package.

Feature Summary

• Integrated dual phase-locked loops support flexible clock inputs including a 32-kHz sleep clock for low-power playback mode.
• Supports differential microphone inputs and stereo line-in with analog low-power loop capabilities from line-in to outputs.
• Includes two vibrator and haptics feedback channels with differential H-bridge drivers for fast motor acceleration.

Applications

• Mobile and smart phones
• Handheld devices
• MP3 players

Procurement Notes

Verify the active production status and RoHS compliance before procurement. Confirm the specific ordering suffix matches the required packaging quantity and moisture sensitivity level. Ensure compatibility with the host processor interface requirements.

Selection Notes

Select this component for designs requiring high integration of audio processing and power management functions. Evaluate the system's power budget against the device's low-power modes and verify that the 120-pin NFBGA package fits the board layout constraints.

Part Context

This part belongs to the Texas Instruments TWL6040 series of audio codecs. It is specifically engineered for OMAP-based systems, providing optimized power consumption and performance through proprietary PDM interfaces and integrated analog front-end components.

Replacement Considerations

Check for alternative packages within the same family, such as the ZQZ variant, noting differences in package type and availability status. Verify functional equivalence if substituting with other members of the TWL60xx series.

FAQ

What is the maximum dynamic range of the DAC channels?

The stereo capless headphone drivers achieve up to 104-dB dynamic range when using the system clock input and DAC path high-performance mode.

How does the device handle accessory detection?

The TWL6040 supports accessory plug and unplug detection (PLUGDET) and periodic accessory button press detection to minimize current consumption in sleep mode.

What are the supported system clock frequencies?

The device supports 12-, 19.2-, 26-, and 38.4-MHz system clock inputs, or a 32-kHz sleep clock for low-power playback mode.
