192 kHz, 24-Bit DAC
ADAU1966A
FEATURES
GENERAL DESCRIPTION
Differential or single-ended voltage DAC output
The ADAU1966A is a high performance, single-chip digital-to-
114 dB DAC dynamic range, A-weighted, differential
analog converter (DAC) that provides 16 DACs with differential or
−97 dB total harmonic distortion plus noise (THD + N),
single-ended outputs using the Analog Devices, Inc., patented
differential
multibit sigma-delta (Σ-Δ) architecture. A serial peripheral interface
110 dB DAC dynamic range, A-weighted, single-ended
(SPI)/I2C port is included, allowing a microcontroller to adjust
−95 dB THD + N, single-ended
volume and many other parameters. The ADAU1966A operates
2.5 V digital and 3.3 V analog and input/output (I/O) supplies
from 2.5 V digital and 3.3 V analog supplies. A linear regulator
299 mW total quiescent power
is included to generate the digital supply voltage from the analog
Phase-locked loop (PLL) generated or direct master clock
supply voltage. The ADAU1966A is available in an 80-lead LQFP.
Low electromagnetic interference (EMI) design
Linear regulator driver to generate digital supply
Supports 24-bit and 32 kHz to 192 kHz sample rates
Low propagation 192 kHz sample rate mode
Log volume control with autoramp function
Temperature sensor with digital readout ±3°C accuracy
SPI and I2C controllable for flexibility
Software-controllable clickless mute
Software power-down
Right justified, left justified, I2S, and TDM modes
Master and slave modes with up to 16-channel input/output
80-lead LQFP package
The ADAU1966A 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 ADAU1966A
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

function of the pin, for example, SCLK, when only that function
