DESCRIPTION
The TLV320DAC3202 is a high fidelity and low power headphone amplifier with integrated DAC and power rails.
The small solution size and highly efficient operation maximizes battery life and performance. The digital audio
interface supports industry standard formats such as I2S and PCM. Many features of this device such as volume
setting, data width and sampling rate are configurable for optimum flexibility and efficiency. The headset power
control automatically adjusts the rail voltage based on the input signal to maximize efficiency and performance.
The control interface uses an industry standard I2C controller for ease of operation and reduction in device pin
count.
