Texas Instruments TAA5212 Stereo Audio Analog-to-Digital Converter
Texas Instruments TAA5212 Stereo Audio Analog-to-Digital Converter (ADC) is a high-performance stereo audio ADC with 2VRMS differential input and 119dB dynamic range. The TAA5212 supports differential and single-ended line/microphone input signals with AC or DC coupling configuration options. The TAA5212 integrates programable channel gain, digital volume control, a low-jitter phase-locked loop (PLL), and a programmable digital high-pass filter (HPF). It also includes programmable EQ and bi-quad filters, decimation filters with low-latency and ultra low-latency options, and supports sample rates up to 768kHz. The TAA5212 supports time-division multiplexing (TDM), I2S, or left-justified (LJ) audio formats in controller and target modes and can be controlled with I2C or SPI. These integrated high-performance features and a single supply operation make Texas Instruments TAA5212 an excellent choice for space-constrained audio applications.
