Overview
The TLV320AIC3111IRHBT is a low-power stereo audio codec manufactured by Texas Instruments, designed for portable and battery-operated applications. It features a 32-bit resolution with a maximum sampling rate of 192 kHz. The device integrates one analog-to-digital converter (ADC) and two digital-to-analog converters (DAC). It operates within a supply voltage range of 2.7 V to 3.6 V and supports serial I2C interfaces for control. Key performance metrics include a signal-to-noise ratio of 91 dB for the ADC and 95 dB for the DAC, with total harmonic distortion plus noise specified at -85 dB for the ADC and -82 dB for the DAC. It functions between -40°C and +85°C in a VQFN-32 package.
Feature Summary
- Integrates high-fidelity stereo audio conversion capabilities with dedicated ADC and DAC channels.
- Supports high-resolution audio processing up to 32 bits and sampling rates reaching 192 kHz.
- Utilizes a compact VQFN-32 surface-mount package suitable for space-constrained designs.
Applications
- Portable media players and handheld audio devices
- Mobile communication terminals requiring integrated audio processing
- Battery-powered consumer electronics with strict power constraints
Procurement Notes
Verify the specific suffix IRHBT against the manufacturer's datasheet to confirm the tape-and-reel packaging configuration and temperature grade. Ensure compatibility with the target system's I2C bus voltage levels and check moisture sensitivity classification requirements for storage and reflow soldering processes prior to assembly.
Selection Notes
Select this component when a single-chip solution for stereo audio input and output is required with high dynamic range specifications. Compare against the TLV320AIC3100 series if lower power consumption at reduced performance or different voltage domains are prioritized over the 192 kHz maximum sampling capability.
Part Context
This part belongs to the TLV320AIC3111 family of low-power audio codecs from Texas Instruments. It shares architectural similarities with the TLV320AIC3100 series but offers distinct performance characteristics regarding sampling rates and power management profiles tailored for modern portable multimedia applications.
Replacement Considerations
The TLV320AIC3100IRHBT is a documented alternative within the same product family. Verify pinout compatibility and functional equivalence regarding ADC/DAC counts before substitution.
