Low Power Audio AmplifierFeatures: Wide operating supply voltage range (2.0V to 16V), allows telephone line powered applications Low quiescent supply current (2.7 mA typ.) for battery powered applications Chip disable input to power down the IC Low power-down quiescent current (65AmicroA typ.) Drives a wide range of speaker loads (8.0 and up) Output power exceeds 250 mW with 32 speaker Low total harmonic distortion (0.5% typ.) Gain adjustable from 46dB for voice band Requires few external components Operating temperature: -20C to 70C Maximum load resistance: 100 Typical gain bandwidth product: 1.5MHz Maximum output current: 250mA Maximum quiescent current: 5mA @ 16V Total harmonic distortion noise: 0.6% @ 32/200mW, 0.5% @ 80/20mW Maximum input bias current: 0.2AmicroA @ 6V
