Product Introduction

Overview

The AD8018AR-EVAL is an evaluation board designed for the AD8018, a dual, high-speed, low-cost operational amplifier produced by Analog Devices Inc. This amplifier is particularly suited for applications requiring high output current and low distortion, such as in xDSL modems. The AD8018 is fabricated using Analog Devices’ high-speed XFCB (eXtra Fast Complementary Bipolar) process, which ensures high bandwidth and fast slew rates while minimizing distortion and power consumption.

Output Voltage Swing Rail-to-rail output, within 0.5 V of supply rails
Distortion Low distortion, –82 dBc out-of-band SFDR
Package Options 8-lead SOIC, 14-lead TSSOP
Operating Temperature Range –40°C to +85°C
Power Dissipation 650 mW (SOIC), 565 mW (TSSOP)

Key Features

  • High output current capability: up to 400 mA into 10 Ω differential load.
  • Low distortion: maintains –82 dBc out-of-band SFDR.
  • Rail-to-rail output voltage swing: within 0.5 V of the supply rails.
  • High bandwidth and fast slew rate: ensures minimal distortion.
  • Low power consumption: quiescent current of 9 mA per amplifier.
  • Flexible standby and shutdown modes: controlled by two digital logic bits (PWDN1 and PWDN0).
  • Stable with capacitive loads and thermal overload protection.
  • Compact packaging: available in 8-lead SOIC and 14-lead TSSOP packages.

Applications

  • xDSL modems: where high output current and low distortion are essential.
  • Line drivers: particularly in single-supply configurations.
  • Battery-powered applications: due to low power consumption.
  • Industrial and automotive systems: requiring robust performance and wide operating temperature ranges.
