The AD8391 is an xDSL line driver amplifier designed for single-supply xDSL systems. It operates on a voltage range of 3V to 12V and provides low distortion signals. It is suitable for low power applications such as line powered and battery backup systems. The amplifier outputs more than 250mA of current while maintaining -82dBc of SFDR at 100kHz on 12V. It also features a flexible power-down function controlled by a digital control line.
The AD8391 is a dual-channel, low-power xDSL line driver amplifier designed for single-supply operation between 3V and 12V. It is intended for applications such as line-powered and battery backup systems where low power consumption is essential. The device features a 1-pin digital control line for power-down, allowing the amplifier to be biased to full power, standby, or shutdown states.
