7 / 26 page CS3511 DS845PP2 7 AC ELECTRICAL CHARACTERISTICS Test Conditions (unless otherwise specified): AGND = DGND = PGND = 0 V; All voltages with respect to ground; TA = 25°C; VP = 12 V; RL =8 Ω full-bridge; GAIN1 = 0, GAIN0 = 1; 10 Hz to 20 kHz Measurement Bandwidth; Per- 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.
