CS43130-CNZ

Digital To Analog Converters Overview

The CS43130-CNZ is a high-performance, 32-bit stereo audio DAC with integrated ground-centered headphone amplifiers and impedance detection. It supports sampling rates up to 384 kHz and features an enhanced delta-sigma oversampling architecture with low clock jitter sensitivity. The device delivers 130-dB dynamic range (A-weighted) and -108-dB THD+N. Headphone outputs provide 30 mW into 32 ohms or 5 mW into 600 ohms per channel. It includes an integrated PLL supporting various MCLK rates, I2C control up to 1 MHz, and DSD path support. The component operates within a voltage range of 1.66 V to 1.94 V for analog and digital supplies, functioning in commercial temperatures from -10°C to +70°C.

• Built-in digital signal processing including five selectable filter responses and direct DSD stream handling

Digital To Analog Converters Applications

• Smartphones and tablets
• Portable media players and laptops
• Digital headphones and powered speakers
• AVR and home theater systems
• Blu-ray/DVD/SACD players and pro audio equipment

Digital To Analog Converters Procurement Notes

Verify the specific package type required, as the CS43130 family includes both 40-pin QFN and 42-ball WLCSP options. Confirm that the CNZ suffix corresponds to the QFN package variant suitable for surface mount assembly. Ensure compatibility with standard I2C bus voltages and check for any specific RoHS compliance documentation requirements prior to finalizing procurement orders.

Digital To Analog Converters Selection Notes

Select this component when system design requires high-fidelity audio conversion with integrated headphone driving capability to minimize bill-of-materials costs. It is suitable for applications needing precise volume control via I2C and flexible clocking through the internal PLL. Consider the 40-pin QFN package for PCB layout constraints requiring exposed thermal pads for heat dissipation during continuous operation.

Digital To Analog Converters Part Context

The CS43130 belongs to Cirrus Logic's MasterHIFI series of high-performance audio converters. It shares architectural similarities with the CS43131 but lacks certain advanced impedance measurement features found in later iterations. This part represents a mature solution for premium audio applications where balanced performance and power efficiency are critical design parameters.

Digital To Analog Converters Replacement Considerations

CS43131-CNZ serves as a functional substitute offering similar audio specifications with added impedance detection features.
