Features

• NCS5651MNTXG Dual Operational Amplifier, ON Semiconductor. The NCS5651 is a high efficiency, class A/B, low distortion power line driver. It is optimised to accept a signal from a Power Line Carrier modem. It incorporates two Operational Amplifiers (op-amps). The output op-amp is designed to drive up to 2 A peak. At the output current of 1.5 A, the output voltage is guaranteed to swing within 1 V or less of either rail, giving the user improved SNR. In addition to the output amplifier, the small-signal provided op-amp can be configured as a unity gain follower buffer or it can provide a stage of a 4-pole low pass filter. The NCS5651 offers a current limit programmable with a single resistor. The device provides also two independent thermal flags with hysteresis. The thermal warning flag shows when the internal junction temperature has reached a user programmable thermal warning threshold. The thermal error flag indicates that the internal junction temperature has exceeded 150°C. Typical applications are Power Line Communication (PLC) applications, actuators and motors drivers and any applications where a robust power amplifier is required. Features.
