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 = 40MHz, 0dB 1kHz output, I2S input, output unloaded, internal DVDD, all external supply voltages at

nominal center values

2) Measured 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 8. External +1.3V DVDD is required above the

operating frequencies described on page 8. The external supply voltage should be greater than the internal +1.2V supply so the

internal regulator is disabled. DVDD current is measured with MCLK = 100MHz.
