The Le87100 device is a single-channel differential amplifier designed to drive PLC high-power signals. The Le87100 device contains a pair of wide-band amplifiers designed with Microchip’s HV15 bipolar SOI process for high-power output with low-power consumption. Line driver gain is set externally to the device. The device can be powered from a single high-voltage supply or from dual supplies. The device can be programmed to one of three preset bias levels to optimize power and performance. In addition, the line driver features a power down state, which forces low-power and high-impedance mode for receive transmissions or for idle operations. The control pins respond to input levels that can be generated with a standard GPIO, but are tolerant of higher voltage logic levels. The Le87100 device is available in a 16-pin (4 mm x 4 mm) QFN package with an exposed pad for enhanced thermal conductivity.
