MS1808 96kHz 24 position ΔΣ ADC

Audio Performance and Resolution

• MS1808: The MS1808 boasts a 24-bit resolution with a high SNR (Signal-to-Noise Ratio) of 105 dB, delivering exceptional audio fidelity and low distortion. This makes it an ideal choice for high-end audio applications, ensuring clear and accurate audio signal conversion, especially in professional audio equipment, consumer electronics, and high-resolution audio systems.

• PCM1808PWR: The PCM1808PWR also offers 24-bit resolution, but with a slightly lower SNR of 102 dB. While still providing good audio quality, the MS1808’s higher SNR ensures a more accurate representation of the original audio signal, making it the preferred option in applications where audio precision is critical, such as studio recording and audiophile equipment.

Power Consumption and Efficiency

• MS1808: The MS1808 is designed with power efficiency in mind, featuring low power consumption modes and operating at a typical current draw of 3.5 mA. This makes the MS1808 ideal for portable and battery-operated devices where energy conservation is a priority. Additionally, the chip's low quiescent current minimizes the overall system power consumption.

• PCM1808PWR: The PCM1808PWR has a higher power consumption compared to the MS1808, with a typical current draw of 4.5 mA. While this is still within acceptable limits for many audio applications, the MS1808’s lower power consumption provides a distinct advantage in battery-powered or energy-sensitive systems, helping to extend battery life and reduce heat dissipation.

Dynamic Range and Signal Integrity

• MS1808: One of the standout features of the MS1808 is its dynamic range of 105 dB, offering exceptional signal integrity and the ability to capture both low and high-end audio signals without distortion. This makes it highly suitable for professional audio systems that require precise handling of a wide range of sound levels and dynamic nuances.

• PCM1808PWR: The PCM1808PWR has a slightly lower dynamic range of 102 dB, which may be sufficient for many audio applications, but falls short when it comes to applications requiring the highest levels of signal fidelity. The MS1808's superior dynamic range ensures that it is better equipped to handle demanding audio systems where clear and undistorted signal conversion is crucial.

Integration and Peripheral Support

• MS1808: The MS1808 is highly integrated, offering several on-chip features, including programmable gain control (PGC), low-pass filters, and voltage reference options. This integration simplifies the design process and reduces the need for external components, leading to cost savings and smaller PCB sizes in end products. Its flexibility allows for easier customization to meet specific application requirements.

• PCM1808PWR: While the PCM1808PWR does offer basic integration features, it does not provide the same level of peripheral support as the MS1808. The absence of programmable gain control or integrated filters means that designers may need to incorporate additional external components to achieve similar functionality, increasing both the BOM (Bill of Materials) and the overall complexity of the design.

Application Versatility and Customization

• MS1808: The MS1808 is designed with flexibility in mind, supporting a wide range of audio applications, including high-fidelity audio systems, broadcast equipment, home theater systems, and musical instruments. Its ability to offer user-customizable settings, such as filter cutoffs and gain levels, gives designers the ability to tailor the chip's performance to meet specific application needs.

• PCM1808PWR: The PCM1808PWR is suitable for many audio applications, but lacks the same level of customization available with the MS1808. Its more limited configurability means that it may not be the best fit for systems requiring high levels of customization or those that must adapt to evolving needs or specific use cases.

Cost and Design Complexity

• MS1808: The MS1808 provides a cost-effective solution for high-performance audio conversion, thanks to its high integration and low power consumption. This means that designers can achieve advanced features and high-quality audio without significant additional costs or increased design complexity. Its flexibility and performance make it an attractive choice for both consumer electronics and professional audio systems.

• PCM1808PWR: The PCM1808PWR may be less expensive initially, but its lower level of integration and higher power consumption could lead to increased overall costs due to the need for additional components. Additionally, the PCM1808PWR might increase design complexity in applications that require the same level of performance and flexibility as the MS1808.
