216kHz Audio A/D Converter Targets Professional, Consumer Audio Applications

San Jose, California, October 9th, 2003 —
Asahi Kasei Microsystems Semiconductor, Inc. (AKM), a supplier of audio ICs for professional and consumer markets introduced the AK5385A, an enhanced 24-bit 2-channel A/D converter supporting sample rates up to 216kHz. The high-performance device is designed for professional and consumer electronics applications that require a high degree of resolution, including DVD-A and professional 192kHz recording formats.

The AK5385A features fully differential inputs and an enhanced dual-bit architecture that provides an impressive 114dB signal-to-noise ratio (SNR). A key feature of the AK5385A is its pin-compatibility with the current AKM lineup of high performance analog-to-digital converters, including the audio industry's highest performing ADC, the AK5394A. In all, there are five pin-compatible parts in this A/D family, allowing designers to use the AK5385A and easily change price and performance by using a pin-compatible alternative. The chip supports 24-bit audio formats and sample rates from 8kHz to 216kHz, making it suitable for high-definition audio for professional and consumer applications.

The AK5385A uses a 5-volt analog supply and can use a 3 to 5.25-volt digital supply, making it compatible with industry standard digital signal processors (DSPs).

Available in a space-saving 28-pin VSOP package, the AK5385A engineering samples and evaluation boards are available now. The part is priced at $5.00 in 5K quantities.
