• Description: 10W Stereo/15W Mono Filterless Spread-Spectrum Class D Amplifiers
• Manufacturer: Maxim Integrated Products

ELECTRICAL CHARACTERISTICS (continued)

GND (f
Typical values are at T
Note 1: All devices are 100% production tested at +25°C. All temperature limits are guaranteed by design.
Note 2: Testing performed with a resistive load in series with an inductor to simulate an actual speaker load. For R
Note 3: PSRR is specified with the amplifier inputs connected to GND through C
Note 4: The MAX9704 continuous 8Ω and 16Ω power measurements account for thermal limitations of the 32-pin TQFN-EP package.
