Overview
Delta-sigma stereo, audio DAC contains: reference voltage, control logic, digital buffers I2S interface (ws, sd, sck, gpio), two identical channels L and R: 2-order delta-sigma modulator, current steering DAC, low pass filter, analog buffer. Delta-sigma stereo, audio DAC requires 2.8 ÷3.6 V analog supply, 1.62 ÷ 1.98 V digital supply, reference current 4.95 ÷ 5.05 uA, input clock with duty cycle 45 ÷ 55 %. Delta-sigma stereo, audio DAC supports standby mode. There is the ability to configure the operating modes of the delta-sigma stereo, audio DAC with digital registers: register mode<2:0> controls the modes of the delta-sigma stereo, audio DAC and I2S interface (sd, ws), register mode_sck<2:0> controls the modes of I2S interface (sck), register mode_gpio<2:0> controls the modes of I2S interface (gpio). There is the ability to configure current consumption of the delta-sigma stereo, audio DAC with digital register: register adj_idc_buff<3:0> adjusts current of the analog buffer, register adj_idc_cs<3:0> adjusts current of the current steering DAC, register adj_idc_lpf<4:0> adjusts current of the low pass filter, signal enrc adjusts current of current steering DAC changing linearity of the current steering DAC.
Register adj_idc_cs<3:0> is also controls output voltage peak to peak.

Specifying a PLL Part 1: Calculating PLL Clock Spur Requirements from ADC or DAC SFDR
In high end RF systems, such as 5G radios, the requirements are so stringent that the source of this strongest unwanted tone can be the PLL. This article outlines how spurs in the input clock to the ADC or DAC may limit the SFDR. This in turn will set the requirements for the spurs for the input clock (from a PLL), in order to achieve a specific SFDR.
