Cirrus Logic Launches New Pin-Compatible Stereo A/D Converters
Posted Feb 21, 2003

Cirrus Logic Inc. has added two new 24-bit, 192 kHz multi-bit audio analog-to-digital (A/D) converter products to their product line, the CS5340 and CS5341.

These pin-compatible, stereo A/D converters are targeted at mainstream consumer products such as DVD recorders, audio/video receivers, personal video recorders, DVD players with karaoke support, DVD receivers, and set-top boxes. Additional applications include digital mixing consoles, multi-track recording systems, outboard converters and automotive audio systems.

The CS5341 delivers 105 dB dynamic range and 98 dB THD+N in a low-profile 16-pin TSSOP package, as well as 24-bit conversion and support for all standard audio sample rates from 32 kHz to 192 kHz, making it DVD-Audio compatible. The CS5340 is pin compatible with the CS5341 and delivers 101 dB dynamic range and 94 dB THD+N, making it an ideal solution for applications that require the most cost-effective solution. Other key features of both units include proprietary automatic sample rate detection, single power supply operation from 3.3V to 5.0V, a multi-bit Delta-Sigma modulator, a single-ended input architecture, and on-chip level translators for direct interface to external audio processors.

The CS5340 and CS5341 are currently in sample production. The CS5341 is priced at $2.47 in 10,000 quantities, and the CS5340 is priced at $1.92 in 10,000 quantities.
