CS4340-KS datasheet by Cirrus Logic

CS4340-KS Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the CS4340-KS?
  The recommended power-up sequence is to apply VDD first, followed by VDDIO, and then the clock signal. This ensures proper initialization of the device.
• How do I optimize the performance of the CS4340-KS in terms of THD+N?
  To optimize THD+N performance, ensure that the analog input signal is properly filtered and attenuated to prevent overloading the ADC. Additionally, use a high-quality clock source and ensure that the device is operated within its recommended operating conditions.
• What is the maximum input signal amplitude that the CS4340-KS can handle?
  The maximum input signal amplitude that the CS4340-KS can handle is 2.5 Vrms. Exceeding this limit may result in distortion and degradation of the ADC's performance.
• How do I configure the CS4340-KS for differential or single-ended input operation?
  The CS4340-KS can be configured for differential or single-ended input operation through the use of external resistors and capacitors. Refer to the datasheet for specific configuration details and recommendations.
• What is the recommended clock frequency range for the CS4340-KS?
  The recommended clock frequency range for the CS4340-KS is 10 MHz to 50 MHz. Operating the device outside of this range may result in reduced performance or instability.
