Product details
Overview
TLV320AIC3111 from Texas Instruments is a low-power, highly integrated audio codec IC featuring stereo 16-bit DAC (95-dB SNR), mono 16-bit ADC (91-dB SNR), embedded programmable miniDSP, and stereo 1.29-W Class-D BTL speaker amplifier with direct battery connection. It supports 8–192 kHz sample rates, I²S/PCM/DSP/TDM interfaces, and operates from 2.7–5.5 V supply rails.
For engineers reviewing the TLV320AIC3111 datasheet, TLV320AIC3111 pinout, TLV320AIC3111 application, or TLV320AIC3111 equivalent, key selection considerations include its dual-path miniDSP programmability, integrated Class-D speaker driver with 8-Ω BTL output, microphone bias and AGC support, I²C register control, and 5-mm × 5-mm 32-QFN package for space-constrained portable audio designs.
Technical Context
The TLV320AIC3111 integrates analog front-end (MIC bias, PGA, AGC), digital audio processing (dual biquad/FIR filters, bass/treble/EQ), and mixed-signal output stages (Class-D speaker amp + Class-A/B headphone/lineout drivers). Its PLL generates high-speed clocks for miniDSP operation independent of audio interface clocking.
Digital audio routing is fully configurable via I²C registers: DAC outputs can feed either headphone/lineout or Class-D speaker paths; ADC inputs support differential/single-ended mixing with programmable gain (0–59.5 dB in 0.5-dB steps) and impedance selection.

FAQ
What is the maximum output power of the TLV320AIC3111IRHBT Class-D speaker amplifier?
The TLV320AIC3111IRHBT delivers up to 1.29 W into an 8-Ω BTL load when powered from 5.5 V SPLVDD/SPRVDD. At 4.3 V, output is 790 mW; at 3.6 V, it is 540 mW. These values assume 10% THD and proper thermal management using the exposed thermal pad on the 32-QFN package.
Does the TLV320AIC3111IRHBT support I²S interface in both master and slave modes?
Yes, the TLV320AIC3111IRHBT supports I²S, left-justified, right-justified, DSP, and TDM audio interfaces in both master and slave configurations. Timing specifications are provided separately for each mode in the datasheet, with BCLK/WCLK setup/hold and propagation delays validated across IOVDD ranges from 1.1 V to 3.6 V.
Can the TLV320AIC3111IRHBT operate with different supply voltages for analog and digital domains?
Yes, the TLV320AIC3111IRHBT has independent supply domains: AVDD (2.7–3.6 V) for analog circuitry, DVDD (1.65–1.95 V) for digital core, IOVDD (1.1–3.6 V) for I²C and audio interface I/O, and SPLVDD/SPRVDD (2.7–5.5 V) for Class-D outputs. This enables optimal noise isolation and power efficiency in mixed-voltage systems.
How many biquad filters does the embedded miniDSP in the TLV320AIC3111IRHBT support?
The TLV320AIC3111IRHBT contains two independent miniDSP engines: one dedicated to the record (ADC) path supporting up to five biquad sections, and another for the playback (DAC) path supporting up to six biquad sections. Both are fully programmable via I²C register writes and support coefficient loading from host memory.
Is the VOL/MICDET pin on the TLV320AIC3111IRHBT configurable for multiple functions?
Yes, the VOL/MICDET pin on the TLV320AIC3111IRHBT is multifunctional: it can be configured via register settings as either an analog volume control input (0–AVDD range, 128-step resolution) or a microphone detection input that triggers interrupt generation upon plug-in event detection.
