The PCM4202DBRG4 from Texas Instruments is a high-performance, professional-quality digital audio analog-to-digital converter (ADC). This product is designed to offer superior audio performance and functionality, making it an ideal choice for a wide range of applications, including professional audio recording, broadcast studio equipment, and high-end consumer audio products. The PCM4202DBRG4 features a dynamic range of 118 dB and a total harmonic distortion plus noise (THD+N) of -106 dB. This ensures you get clear, high-quality audio conversion, free from distortion and noise. The device operates over a sampling frequency range of 10 kHz to 200 kHz, providing flexibility for different audio applications. One of the key features of this product is its high-pass filter (HPF), which removes the DC component of the input signal to prevent saturation of the ADC and subsequent digital processing circuitry. The HPF has a cutoff frequency of 0.91 Hz at fs = 48 kHz. This feature is particularly useful in audio recording and processing applications where DC offset can be a problem. The PCM4202DBRG4 also includes a digital high-pass filter, digital attenuator, and soft mute function, all of which can be controlled via a serial peripheral interface (SPI) port. This allows for easy integration and control in digital audio systems. Another notable feature is its differential analog inputs, which are designed to handle large input signals without distortion. This makes the PCM4202DBRG4 suitable for professional audio applications where high input levels are common. The PCM4202DBRG4 is available in a compact 28-pin SSOP (DB) package, making it easy to integrate into your design. It operates over a wide temperature range of -40°C to +85°C, ensuring reliable performance in various operating conditions. In conclusion, the PCM4202DBRG4 from Texas Instruments is a high-quality, feature-rich ADC that offers superior audio performance. Whether you're designing professional audio equipment or high-end consumer audio products, this device is an excellent choice that combines high performance with a range of useful features.
