TLV320AIC3104
Overview
The TLV320AIC3104 is a low-power stereo audio codec with stereo headphone amplifier, as well as multiple inputs and outputs that are programmable in single-ended or fully differential configurations. The device includes extensive register-based power control is included, thus enabling stereo 48-kHz DAC playback as low as 14 mW from a 3.3-V analog supply, making the device ideal for portable batter.
- Stereo audio DAC: - 102-dBA signal-to-noise ratio - 16-, 20-, 24-, or 32-bit data - Supports sample rates from 8 kHz to 96 kHz - 3D, bass, treble, EQ, or de-emphasis effects - Flexible power saving modes and performance are available
- Stereo audio ADC: - 92-dBA signal-to-noise ratio - Supports sample rates from 8 kHz to 96 kHz - Digital signal processing and noise filtering available during record
- Six audio input pins: - One stereo pair of single-ended inputs - One stereo pair of fully differential inputs
- Six audio output drivers: - Stereo fully differential or single-ended headphone drivers - Fully differential stereo line outputs
- Low power: 14-mW stereo 48-kHz playback with 3.3-V analog supply
- Ultra-low-power mode with passive analog bypass
- Programmable I/O analog gains
- Automatic gain control (AGC) for record
- Programmable microphone bias level
- Programmable PLL for flexible clock generation
