    PCM1801U/2K Frequently Asked Questions (FAQs)

    • The recommended power-on sequence is to apply VCC first, followed by VREF, and then the analog input signals. This ensures proper device operation and prevents damage to the internal circuitry.
    • To optimize the analog input stage, use a low-pass filter to remove high-frequency noise, and ensure the input signal is within the recommended common-mode voltage range (VCM). Additionally, use a high-impedance source and a low-capacitance layout to minimize signal attenuation.
    • The recommended clock frequency for the PCM1801U/2K is between 2.048 MHz and 12.288 MHz. However, the device can operate with clock frequencies up to 25 MHz, but with reduced performance.
    • The PCM1801U/2K outputs 24-bit data in a MSB-first, left-justified format. Ensure that your receiving device can handle this format, and consider using a FIFO or buffer to handle the data stream.
    • The VREF pin is the reference voltage input for the analog-to-digital converter. Connect a 2.5V reference voltage source to the VREF pin, and ensure it is decoupled with a 10uF capacitor to ground.
