WARNING:

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only and

functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure

to absolute

–maximum–rated conditions for extended periods may affect device reliability.

WARNING: Electrostatic Discharge (ESD) can damage this device. Proper procedures must be followed to avoid ESD when handling this device.

Notes:

(1) fs = 44.1kHz, external MCLK = 22MHz, I2S input, DAC output connected to current-to-voltage converter, internal DVDD, all external

supply voltages at nominal center values

(2) With RESETB held low after setting the soft_start bit in register 14 to 1’b0 to fully ramp the DAC outputs to ground

(3) Internal DVDD should be used except under the conditions described on page 7.

(4) External DVDD current measured at 192kHz sample rate and MCLK = 80MHz.
