Microsemi / Microchip Le87100 Single-Channel Differential Amplifier
Microsemi / Microchip Le87100 Single-Channel Differential Amplifier is designed to drive PLC high-power signals. The Le87100 device contains a pair of wide-band amplifiers designed for a high-power output with low-power consumption. Line driver gain is set externally to the device. A single high-voltage supply or dual supplies can power the device. Le87100 can be programmed to one of three preset bias levels to optimize power and performance. Also, the line driver features a power down state, which forces low-power and high-impedance mode for receive transmissions or 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 Microsemi / Microchip Le87100 device is available in a 16-pin (4mm x 4mm) QFN package with an exposed pad for enhanced thermal conductivity.
