ON Semiconductor’s latest line driver for power line carrier (PLC) communications applications contains an operational amplifier which can be configured as a unity gain follower buffer, or alternatively used to provide the first stage of a 4-pole low pass filter.

The output stage has the capacity drive up to 2A peak into an isolation transformer or simple coil coupling to the mains.

At an output current of 1.5A, the output voltage is guaranteed to swing within 1.0V or less on either rail, ensuring optimal signal-to-noise ratio (SNR) in harsh environments.

The NCS5650 draws 150µA while in shutdown mode. Power supply options are single-sided 6V to 12V and dual balanced ±3.0V to ±6.0V.
 
The devices have an extended junction temperature range of -40 °C to +125 °C. They are offered in a 20-pin, 4 mm x 4 mm x 1 mm, Pb-free, QFN package.
