PRODUCT DESCRIPTION
The AD8079 is a dual, low power, high speed buffer designed to operate on ±5 V supplies. The AD8079’s pinout offers excellent input and output isolation compared to the traditional dual amplifier pin configuration. With two ac ground pins separating both the inputs and outputs, the AD8079 achieves very low crosstalk of less than –70 dB at 5 MHz.
