LE87271EQC [Microchip]

The Le87271 device is a single-channel differential amplifier designed to work in Customer Premise Equipment (CPE) systems. It provides multiple bias levels to optimize power and performance. In addition, the line driver features a power-down state, which forces low power. The control pins respond to input levels that can be generated with a standard GPIO.The Le87271 device is available in a 20-pin (4 mm x 4 mm) QFN package with an exposed pad for enhanced thermal conductivity.
