16-channel audio DAC

25 July 2012 Analogue, Mixed Signal, LSI

Analog Devices has introduced a 16-channel audio D/A converter (DAC) capable of improving audio system performance and reducing power consumption for professional, ‘prosumer’ and automotive audio equipment applications.

The 24-bit ADAU1966 provides 118 dB SNR (signal-to-noise ratio) performance at 32 kHz to 192 kHz sampling rates. This is achieved with power consumption of less than 300 mW for 16-channel operation by running the digital portion of the chip at a lower voltage.

The digital supply can be generated on-chip via a linear regulator, allowing the IC to operate off a single analog supply. Alternatively, the regulator can be bypassed and a separate 2,5 V to 3,3 V supply provided to the chip.

Operating the ADAU1966 with full-scale differential output voltage of 3 Vrms reduces the need for downstream gain and preserves a high SNR against electrically coupled system noise. By using the device’s onboard PLL (phase-locked loop) to derive the internal master clock from an external left/right clock, the IC eliminates the need for a separate high-frequency master clock and can be used with or without a bit clock.

The ADAU1966 is qualified for AEC-100 automotive applications and operates over a -40°C to +105°C temperature range. It also features an SPI/I²C port which allows an external microcontroller to adjust volume and read the chip temperature to within ±3°C.
