Overview
The TLV320AIC3107IYZFR is a low-power stereo audio codec manufactured by Texas Instruments, housed in a 42-DSBGA package. It integrates a stereo headphone amplifier and a mono Class-D speaker driver. The device supports data resolutions of 16, 20, 24, and 32 bits with sampling rates from 8 kHz to 96 kHz. It features two ADCs and two DACs, operating on a minimum supply voltage of 2.7 V and a maximum of 5.5 V for the analog section. The digital core operates between 1.525 V and 1.95 V, while digital I/O ranges from 1.1 V to 3.6 V. The component functions within a temperature range of -40°C to +85°C.
Feature Summary
- Integrates stereo headphone amplifiers and a mono Class-D BTL speaker driver for versatile output configurations.
- Supports flexible input programming with seven pins configurable as single-ended or fully differential inputs.
- Includes programmable power control modules enabling ultra-low power modes with passive analog bypass.
Applications
- Mobile phones
- Digital cameras
- Portable media players
Procurement Notes
Verify the specific suffix 'YZFR' against the manufacturer's official documentation to confirm the exact package type and reel specifications. Ensure compatibility with the required supply voltages and interface protocols before integration. Cross-reference the datasheet revision date to validate all electrical characteristics and pin assignments.
Selection Notes
Select this component when a compact solution combining high-performance audio conversion with integrated power amplification is required. It is suitable for battery-operated devices due to its low power consumption features. Consider the 42-DSBGA package size constraints and the need for external passive components for the Class-D amplifier stage during design.
Part Context
This part belongs to the TLV320AIC3107 series of low-power stereo codecs from Texas Instruments. It is designed for portable audio applications requiring integrated amplification. The series offers various packaging options, including QFN and DSBGA, to suit different board space requirements.
Replacement Considerations
Check for other members of the TLV320AIC31xx family that may offer similar amplification capabilities but different pinouts or performance metrics. Verify if alternative packages like the 40-QFN variant provide sufficient interchangeability without redesigning the PCB layout.
