Instructions for Use:
Power Supply:
- Ensure the supply voltage (VDD) is within the specified range of 2.7 V to 5.5 V.
- Connect a decoupling capacitor (typically 0.1 μF) close to the power pins to stabilize the supply.
Digital Inputs:
- The digital inputs must be driven with differential signals.
- Logic high levels should be at least 0.8 V, and logic low levels should be no more than 0.2 V.
Output Configuration:
- The PCM1716E/2K can drive a load directly or through an external buffer.
- Do not exceed the maximum output current of 20 mA per channel.
Signal Quality:
- For optimal performance, ensure the signal-to-noise ratio (SNR) is maintained at 104 dB or better.
- Keep the total harmonic distortion plus noise (THD+N) below 0.0009% for high-quality audio.
Temperature Considerations:
- Operate the device within the temperature range of -40°C to 85°C.
- Store the device in an environment where temperatures do not exceed -65°C to 150°C.
Power Consumption:
- At 3.3 V and a sampling rate of 44.1 kHz, the typical power consumption is 15 mW.
Layout and Grounding:
- Use a ground plane to minimize noise and improve signal integrity.
- Place the device as close as possible to other components in the signal path to reduce trace lengths.
Initialization:
- Refer to the datasheet for specific initialization sequences if required by your application.
Handling:
- Handle the device with care to avoid static damage.
- Follow standard ESD (Electrostatic Discharge) precautions during handling and assembly.
