Audio converter boasts wide sampling rate

San Jose, Calif. — AKM Semiconductor's low-cost, audio analog-to-digital (A/D converter) for audio applications touts a dynamic range of 102 dB signal-to-noise ratio (SNR) and -96 dB total harmonic distortion plus noise (THD+N).

The dual-channel, 24-bit, 192-kHz stereo A/D converter, with a wide sampling rate of 8 Khz to 216 Khz, is intended for use in A/V receivers, automotive amplifiers, DVD recorders, professional audio equipment, and
musical instrument applications.

The AK5359 uses AKM's proprietary dual-bit Delta-Sigma techniques. An integrated high-pass filter is used to eliminate DC offset. The chip requires no external components because all inputs are single-ended. The A/D converter operates in both master and slave modes and has two audio formats, left justified and I2S.

The AK5359 uses a 5-volt analog supply and a 2.7 to 5.5-V digital supply, making it
compatible with industry standard DSPs.

Available in a space-saving 16-pin TSSOP package, the AK5359 comes in two
temperature versions, -20°C to +85&dec;C (AK5359ET) and -40°C to +85°C (AK5359VT).

Priced from $1.43 in 10k unit volumes, evaluation boards and
samples are available now. Click here for the AK5359 data sheet.
