ADAU1962AWBSTZ-RL
DAC 12CH Delta-Sigma 24Bit 80Pin LQFP T/R
Product Details
The ADAU1962A is a high performance, single-chip digital-to-analog converter DAC that provides 12 DACs with differential or single-ended outputs using the Analog Devices, Inc., patented multibit Σ-Δ architecture. A serial peripheral interface SPI/I2C port is included, allowing a microcontroller to adjust volume and many other parameters. The ADAU1962A operates from 2.5 V digital and 3.3 V analog supplies. A linear regulator is included to generate the digital supply voltage from the analog supply voltage. The ADAU1962A is available in an 80-lead LQFP.
The ADAU1962A is designed for low EMI. This consideration is apparent in both the system and circuit design architectures. By using the on-board PLL to derive the internal master clock from an external left-right frame clock LRCLK, the ADAU1962A can eliminate the need for a separate high frequency master clock and can be used with or without a bit clock. The DACs are designed using the latest Analog Devices continuous time architectures to further minimize EMI. By using 2.5 V digital supplies, power consumption is minimized, and the digital waveforms are a smaller amplitude, further reducing emissions.
Note that throughout this data sheet, multifunction pins, such as SCLK/SCL, are referred to by the entire pin name or by a single function of the pin, for example, SCLK, when only that function is relevant.
