AC ELECTRICAL CHARACTERISTICS

Test Conditions (unless otherwise specified): AGND = DGND = PGND = 0 V; All voltages with respect to ground;

formance measurements taken with a differential 997 Hz sine wave and AES17 measurement filter; Stereo Full-

Bridge measurements taken through the Full-Bridge Output Filter shown in Figure 4 on page 15.

Notes:

5.

See Figure 5 on page 17.

6.

dBi is referenced to the input signal amplitude resulting in the specified output power at THD+N<1%. See

“Parameter Definitions” on page 21 for more information.

7.

See Section 4.2 “Dynamic DC Offset Calibration” on page 12.
