Four ADCs/Eight DACs with PLL,

192 kHz, 24-Bit Codec

AD1937

GENERAL DESCRIPTION

FEATURES

The AD1937 is a high performance, single-chip codec that provides

four analog-to-digital converters (ADCs) with differential input

and eight digital-to-analog converters (DACs) with differential

output, using the Analog Devices, Inc., patented multibit sigma-

delta (Σ-Δ) architecture. An I²C® port is included, allowing a

microcontroller to adjust volume and many other parameters.

The AD1937 operates from 3.3 V digital and analog supplies.

The AD1937 is available in a 64-lead (differential output) LQFP.

PLL-generated clock or direct master clock

Low EMI design

112 dB DAC/107 dB ADC dynamic range and SNR

−96 dB THD + N

Single 3.3 V supply

Tolerance for 5 V logic inputs

Supports 24-bits and 8 kHz to 192 kHz sample rates

Differential ADC input

Differential DAC output

Log volume control with autoramp function

I²C-controllable for flexibility

Software-controllable clickless mute

Software power-down

Right-justified, left-justified, I²S, and TDM modes

Master and slave modes up to 16-channel input/output

Available in a 64-lead LQFP

The AD1937 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 master clock from the

LR (frame) clock or from an external crystal, the AD1937 elimi-

nates the need for a separate high frequency master clock and

can also be used with a suppressed bit clock. The DACs and

ADCs are designed using the latest Analog Devices continuous

time architecture to further minimize EMI. By using 3.3 V

supplies, power consumption is minimized and further

reduces emissions.
