2.2 Codec

The built-in codec has a high Signal-to-Noise Ratio (SNR) performance and it consists of an ADC, a DAC and additional analog circuitry.
Note: The internal DAC is not supported in the IS2064GM-0L3 variant.
Note: The internal DAC supports 16-bit resolution. 24-bit I2S port requirements are met by adding trailing zeros in LSBs.

The following figures illustrate the dynamic range and frequency response of the codec.

Figure 2-3. CODEC DAC DYNAMIC RANGE
Note: The data corresponds to the 16 Ohm load with 2.8V operating voltage and +25ºC operating temperature.
Figure 2-4. CODEC DAC THD+N VERSUS INPUT POWER
Note: The data corresponds to the 16 Ohm load with 2.8V operating voltage and +25ºC operating temperature.

Figure 2-6. CODEC DAC FREQUENCY RESPONSE (SINGLE-ENDED MODE)
Note: The DAC frequency response corresponds to Single-Ended mode with a 47 μF DC block capacitor.
