3 / 21 page  10W Stereo/15W Mono, Filterless, Spread-Spectrum, Class D Amplifiers _______________________________________________________________________________________ 3 ELECTRICAL CHARACTERISTICS (continued) (VDD = 15V, GND = PGND = 0V, SHDN ≥ VIH, AV = 16dB, CSS = CIN = 0.47µF, CREG = 0.01µF, C1 = 100nF, C2 = 1µF, FS1 = FS2 = GND (fS = 660kHz), RL connected between OUTL+ and OUTL- and OUTR+ and OUTR-, TA = TMIN to TMAX, unless otherwise noted. Typical values are at TA = +25°C.) (Notes 1, 2) PARAMETER SYMBOL CONDITIONS MIN TYP MAX UNITS RL = 4 Ω 10 RL = 8 Ω 15 Continuous Output Power (MAX9703) PCONT THD+N = 10%, VDD = 16V, f = 1kHz, TA = +25°C, tCONT = 15min (Note 4) RL = 16 Ω, VDD = 24V 18 W RL = 4 Ω 2x5 RL = 8 Ω 2x10 Continuous Output Power (MAX9704) PCONT THD+N = 10%, VDD = 16V, f = 1kHz, TA = +25°C, tCONT = 15min (Note 4) RL = 16 Ω, VDD = 24V 2x16 W Total Harmonic Distortion Plus Noise THD+N fIN = 1kHz, either FFM or SSM, RL = 8 Ω, POUT = 4W 0.07 % FFM 94 BW = 22Hz to 22kHz SSM 88 FFM 97 Signal-to-Noise Ratio SNR RL = 8 Ω, POUT = 10W, f = 1kHz A-weighted SSM 91 dB Crosstalk Left to right, right to left, 8 Ω load, fIN = 10kHz 65 dB FS1 = L, FS2 = L 560 670 800 FS1 = L, FS2 = H 940 FS1 = H, FS2 = L 470 Oscillator Frequency fOSC FS1 = H, FS2 = H (spread-spectrum mode) 670 ±7% kHz POUT = 15W, f = 1kHz, RL = 8 Ω 78 Efficiency η POUT = 10W, f = 1kHz, RL = 16 Ω 88 % Regulator Output VREG 6V DIGITAL INPUTS ( SHDN, FS_, G_) VIH 2.5 Input Thresholds VIL 0.8 V Input Leakage Current ±1µA 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 RL = 8 Ω, L = 68µH. For RL = 4 Ω, L = 33µH. Note 3: PSRR is specified with the amplifier inputs connected to GND through CIN. Note 4: The MAX9704 continuous 8 Ω and 16Ω power measurements account for thermal limitations of the 32-pin TQFN-EP package. Continuous 4 Ω power measurements account for short-circuit protection of the MAX9703/MAX9704 devices. |
