Overview

The TLV320ADC3101 is a low-power, stereo audio Analog-to-Digital Converter (ADC) featuring an integrated miniDSP for custom signal processing. It supports sampling rates up to 96 kHz at 24-bit resolution and includes six analog inputs to accommodate multiple microphones or line-in configurations. This device is particularly effective for systems requiring hardware-accelerated audio effects like noise cancellation or volume leveling without taxing the primary system controller.

Why Choose This Part

The integrated miniDSP architecture allows for offloading intensive audio algorithms from the host processor, reducing overall system power consumption and complexity. It provides high flexibility with support for I2S, DSP, TDM, and PCM interfaces, alongside a wide analog supply range of 2.6V to 3.6V.

Applications

Smart Speakers
Utilizes the integrated miniDSP for beamforming and noise reduction in multi-microphone arrays.
Voice-Activated Systems
Low-power stereo recording with automatic gain control (AGC) for reliable voice command capture.
Portable Audio Recorders
High-fidelity 24-bit 96kHz recording with ultra-low power consumption of only 17mW during stereo operation.
Communication Headsets
Real-time equalization and acoustic echo cancellation processed on-chip to reduce latency.
