Features • High Supply Voltage: ±50V max • Low Distortion: 0.01% • Low Input Noise: 3 µV • High Supply Rejection: 90 dB • Gain and Bandwidth Selectable • Dual Slope SOA Protection • Shutdown Pin Description The LM391 audio power driver is designed to drive external power transistors in 10 to 100 watt power amplifier designs. High power supply voltage operation and true high fidelity performance distinguish this IC. The LM391 is internally protected for output faults and thermal overloads; circuitry providing output transistor protection is user programmable.
