Cirrus Logic CS430x High Performance DACs

Cirrus Logic CS430x High Performance Digital-to-Analog Converters (DACs) feature 2-channel, 4-channel, and 8-channel DACs with high-resolution 32-bit digital architecture. These DACs incorporate a proprietary analog FIR architecture to reduce out-of-band noise and minimize the external component requirements. The CS430x DACs' digital input is supported via the Audio Serial Port (ASP) at sample rates up to 768kHz. These DACs provide low-latency digital interpolation filters and support multichannel operation in I2S, left-justified, and TDM data formats. The CS430x DACs are configured using a control interface that supports both I2C and SPI modes of operation.

The CS430x DACs support a 1.8V to 3.3V digital input/output voltage supply range and operate from -40°C to 85°C temperature range. These DACs are available with a 0.4 mm pitch in a 48-pin QFN package. Typical applications include A/V receivers, digital mixing consoles, high-performance speakers and soundbars, DAW interfaces, and musical instruments.
