Cirrus Logic's new 24-bit DAC with on-chip line driver

Cirrus Logic introduced the CS4353, 24-bit digital-to-analog converter (DAC), for digital audio applications. This CS4353 is the third generation Cirrus Logic audio DAC with integrated 2VRMS line driver from a single 3.3-Volt power supply. Other DACs that feature a line driver require noisy high voltage power supplies.
It significantly simplifies the design of analog output sections circuitry by reducing the need for multiple system components and lowering implementation cost.
It supports all audio sampling rates up to 192 kHz, and is based on a fifth-order multi-bit Delta Sigma converter architecture with low latency digital filtering to provide 106 dB dynamic ranges and -93 dB THD+N. Its ground-centered output architecture not only improves low frequency response but also allows for the removal of external DC blocking capacitors and any pop prevention circuitry.

The device is also ideal for other digital audio equipment such as effects processors, musical instruments, digital audio recorders and automotive audio systems.

Pricing: $1.28 in 0K quantities.
Packaging: 24-pin QFN package
