AD8018ARUZ-REEL7

The AD8018ARUZ-REEL7 is a high-performance, dual-channel, high-speed amplifier from Analog Devices Inc. (ADI). Fabricated with ADI’s high-speed XFCB (eXtra Fast Complementary Bipolar) process, this amplifier is capable of driving low distortion signals to within 0.5 V of the power supply rail. Each amplifier channel can drive up to 400 mA of current into a 10 Ω differential load, while maintaining an out-of-band SFDR (Spurious Free Dynamic Range) of -82 dBc.

The AD8018ARUZ-REEL7 offers flexible standby and shutdown modes, controlled by two digital logic bits (PWDN1 and PWDN0). These modes allow the amplifier to be placed into one of three states: full power, standby (with low impedance outputs), and shutdown (with high impedance outputs). This feature helps in reducing power consumption when the amplifier is not in active use.

With a high bandwidth and fast slew rate, the AD8018ARUZ-REEL7 keeps distortion to a minimum while dissipating a low amount of power. The quiescent current of each amplifier is a mere 9 mA, contributing to its overall efficiency. The amplifier is packaged in a compact 14-lead TSSOP (Thin Small Outline Package), making it suitable for space-constrained applications.

The AD8018ARUZ-REEL7’s low distortion, rail-to-rail output voltage, and high current drive capabilities make it ideal for use in low-cost USB, PCMCIA, and PCI customer premise equipment (CPE) for xDSL systems, such as ADSL, SDSL, VDSL, and proprietary systems. Its high performance and compact packaging make it a valuable component in achieving high dynamic range and low distortion in these applications.

Overall, the AD8018ARUZ-REEL7 combines high speed, low distortion, and high current drive capabilities in a small package, making it an excellent choice for a wide range of high-performance amplification applications.
