|AKM launches low-cost 192kHz audio A/D converter for consumer and
in-car A/V equipment|
Tokyo, Japan, - Asahi Kasei Microsystems Co., Ltd. (AKM) introduced
the AK5359, a low-cost, high quality audio A/D converter for audio/visual applications in pro and consumer equipment
The 24-bit, 192kHz, 2-channel ADC is ideal for DVD recorders, A/V receivers, pro-audio equipment,
musical instrument applications as well as vehicles of all kinds. The pin-compatibility with the current 96kHz ADCs,
AK5357 and AK5381, makes it the perfect choice for applications that require the most cost-effective solution.
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 AK5359 operates in both master and slave modes and has two audio formats, left justified and
I2S. With 102dB dynamic range and 96dB THD+N, the AK5359 is ideally suited to consumer audio applications. The
AK5359 uses a 5-volt analog supply and a 2.7 to 5.5-volt digital supply, making it compatible with industry standard
digital signal processors (DSPs).
The AK5359 comes in two versions, each designed for operating
within a specific temperature range. For consumer applications, the AK5359ET has a temperature range of –20 to 85°C,
while the AK5359VT, designed for use in vehicles, supports wider temperature range of –40 to 85°C. Both are
available in small 16-pin TSSOP package. Evaluation boards and samples are available now.
