Product details
Overview
TLV320AIC3253 from Texas Instruments is a low-power stereo audio codec IC with integrated miniDSP, dual 100dB SNR DACs, stereo digital microphone interface, and programmable headphone drivers. It supports 8kHz–192kHz sample rates, operates from 1.26V–1.95V DVdd and 1.5V–1.95V AVdd, and delivers up to 47mW into 16Ω single-ended loads - ideal for battery-powered mobile handsets and portable computing audio subsystems.
For engineers reviewing the TLV320AIC3253 datasheet, TLV320AIC3253 pinout, TLV320AIC3253 application, or TLV320AIC3253 equivalent, key selection considerations include PowerTune™ configurable power-performance trade-offs, I²C/SPI dual-control interface flexibility, embedded miniDSP programmability, analog bypass mode support, and QFN-24 (RGE) package compatibility with space-constrained PCB layouts.
Technical Context
The TLV320AIC3253 implements a fully register-controlled audio signal path with independent left/right DAC and ADC processing blocks, configurable PLL clock synthesis (512kHz–50MHz input), and flexible pin-multiplexing for BCLK/WCLK/DIN/DOUT across primary and secondary I²S interfaces. Its PowerTune™ architecture enables dynamic adjustment of clock domains, processing depth, and analog bias currents to optimize for voice playback (8kHz) or high-fidelity stereo (192kHz).
It integrates an LDO generating AVdd from 1.9V–3.6V LDOIN, supports dual supply domains (DVdd, IOVdd, AVdd), and provides programmable microphone bias (Micbias Mode 0–3) with up to 3mA sourcing capability. The miniDSP runs at up to 55.3MHz and accepts custom firmware for real-time filtering, equalization, and effects processing in both DAC and ADC paths.
Key Specifications

FAQ
What is the maximum sample rate supported by the TLV320AIC3253IRGET?
The TLV320AIC3253IRGET supports stereo DAC and ADC operation up to 192kHz, with full signal processing path functionality including miniDSP, programmable filters, and headphone driver operation. At 192kHz, PowerTune™ configuration PTM_P1 enables optimized performance, and the device maintains 100dB SNR in DAC path with appropriate clocking (e.g., MCLK = 12.288MHz × 32).
Does the TLV320AIC3253IRGET support digital microphones?
Yes, the TLV320AIC3253IRGET supports stereo digital microphone inputs via its PDM interface on DMDIN/MFP3 and DMCLK/MFP4 pins. This capability is active only when SPI_SELECT = 0 (I²C mode). It supports 64Fs and 128Fs sampling ratios and integrates clock generation and decimation, eliminating need for external PDM-to-I²S converters in TLV320AIC3253IRGET-based designs.
What are the power supply requirements for the TLV320AIC3253IRGET?
The TLV320AIC3253IRGET requires four independent supplies: LDOIN (1.9V–3.6V), AVdd (1.5V–1.95V), DVdd (1.26V–1.95V), and IOVdd (1.1V–3.6V). An integrated LDO generates AVdd from LDOIN, simplifying design. All grounds (AVss, DVss, IOVss) must be tied together with <0.2V potential difference. Minimum DVdd is 1.65V for PLL operation.
Can the TLV320AIC3253IRGET operate in analog bypass mode?
Yes, the TLV320AIC3253IRGET supports analog bypass mode where left/right analog inputs (INL/INR) are routed directly to headphone outputs (HPL/HPR) with ±0.4dB gain accuracy and A-weighted noise of 3mVRMS. This mode disables DAC/ADC paths and miniDSP, achieving ultra-low latency (<1µs) and minimal power consumption - ideal for voice call audio paths requiring deterministic timing.
What package type is used for the TLV320AIC3253IRGET?
The TLV320AIC3253IRGET uses a 4mm × 4mm, 24-pin QFN package with exposed thermal pad (package code RGE). It is distinct from the YZK (2.7mm × 2.7mm WCSP) variant. The RGE package supports standard reflow assembly, offers excellent thermal performance, and is compatible with automated optical inspection (AOI) and X-ray void detection for high-reliability manufacturing.
