Overview
The AD8130AR, produced by Analog Devices Inc., is a low-cost, high-performance differential receiver amplifier designed for the transmission of high-speed signals over twisted-pair cables. It is typically used 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 AD8130AR is known for its stability at a gain of 1, making it versatile for various applications requiring different gain settings. It features user-adjustable gain, which helps compensate for signal losses in the transmission line, and it has a wide power supply range from single +5 V to ±12 V.
