Differential Amplifiers, Analog Devices

Differential Amplifiers by Analog Devices are integrated and optimised for differential signalling applications. These speciality amplifiers have inherent common mode rejection properties that provide a low harmonic distortion with an output gain and phase matching. Applications include driving or receiving signals over long cable lengths, driving a balanced ADC input and looking for complementary outputs.



  • Small signal bandwidth: 260 MHz
  • Ultralow power 1.25mA
  • Extremely low harmonic distortion
    • −122 dB THD at 50 kHz
    • −96 dB THD at 1 MHz
  • Low input voltage noise: 3.9 nV/√Hz
  • 0.35 mV maximum offset voltage
  • Balanced outputs
  • Settling time to 0.1%: 34 ns
  • Rail-to-rail output: −VS + 0.1 V to +VS − 0.1 V
  • Adjustable output common-mode voltage
  • Flexible power supplies: 3 V to 7 V (LFCSP)
  • Disable pin to reduce power consumption
  • Available in LFCSP and SOIC packages


  • Low power ADC drivers
  • Single-ended-to-differential converters
  • Differential buffers
  • Line drivers
  • Medical Imaging
  • Industrial Process Control
  • Portable Electronics
