The 24-bit ADAU1966 16-channel audio D/A converter provides 118-dB SNR performance at 32 kHz to 192 kHz sampling rates and a power consumption of less than 300 mW.The digital supply can be generated on chip via a linear regulator allowing the DAC to operate off a single analog supply. Alternatively, the regulator can be bypassed and a separate 2.5- to 3.3-V supply provided to the chip.
Additional features include full-scale differential output voltage of 3 Vrms, a THD+N of –98 dB, and an SPI/I2C port which allows an external microcontroller to adjust volume and read the chip temperature to within ±3°C. By using the ADAU1966 A/D converter's on-board PLL to derive the internal master clock from an external left/right clock, the part eliminates the need for a separate high frequency master clock and can be used with or without a bit clock. Housed in 80-lead LQFP packages, the part is qualified for AEC-100 automotive applications and operates at a –40° to 105°C temperature range.($6.51 ea/1,000 — available now)
