Overview
The AD8130ARZ-REEL, produced by Analog Devices Inc., is a low-cost, high-speed differential receiver amplifier. It is designed to receive high-speed signals transmitted over twisted-pair cables, typically in conjunction with the AD8131 or AD8132 drivers. This amplifier is suitable for both analog and digital video signals as well as high-speed data transmission. The AD8130 is stable at a gain of 1 and can be adjusted to compensate for losses in the transmission line using user-adjustable gain settings determined by the ratio of two resistor values.
