Cirrus Logic CS530x High Performance ADCs
Cirrus Logic CS530x High Performance Analog-to-Digital Converters (ADCs) feature 2-channel, 4-channel, and 8-channel ADCs with high-resolution 32-bit digital architecture. These ADCs support differential analog input and 32-bit digital output via the Audio Serial Port (ASP) at sample rates up to 768kHz. The CS530x DACs are configured using a control interface that supports both I2C and SPI modes of operation. These ADCs offer synchronized control of an external preamplifier associated with each ADC input path. The CS530x ADCs are integrated with low-latency digital filters and digital volume control.
The CS530x ADCs support a 1.8V to 3.3V digital input/output voltage range and operate from -40°C to 85°C temperature range. These ADCs are available in a commercial‑grade 48‑pin QFN package with a 0.4 mm pitch. Typical applications include A/V receivers, digital mixing consoles,
DAW interfaces, and musical instruments.
