Typ. Max. Unit ICC Supply Current No input signal, no load 68 mA ISTANDBY Standby Current 1) No input signal, Vstdby = Vcc, RL = 8 Ω 1. Standby mode is actived when Vstdby is tied to Vcc 10 1000 nA Voo Output Offset Voltage No input signal, RL = 8 Ω 520 mV Po Output Power THD = 1% Max, f = 1kHz, RL = 8 Ω 1W THD + N Total Harmonic Distortion + Noise Po = 250mW rms, Gv = 2, 20Hz < f < 20kHz, RL = 8 Ω 0.1 % PSRR Power Supply Rejection Ratio 2) f = 217Hz, RL = 8 Ω, RFeed = 22KΩ, Vripple = 200mV rms 2. Dynamic measurements - 20*log(rms(Vout)/rms(Vripple)). Vripple is the surimposed sinus signal to Vcc @ f = 217Hz 75 dB Φ M Phase Margin at Unity Gain RL = 8Ω, CL = 500pF 70 Degrees GM Gain Margin RL = 8Ω, CL = 500pF 20 dB GBP Gain Bandwidth Product RL = 8Ω 2MHz Symbol Parameter Min.
