AD8138 - Differential ADC Driver

General Description

The AD8138 is a major advancement over op amps for differential signal processing.

The AD8138 can be used as a single-ended-to-differential amplifier or as a differential-todifferential amplifier.

Key Features

  • Easy to use, single-ended-to-differential conversion Adjustable output common-mode voltage Externally adjustable gain Low harmonic distortion.
  • 94 dBc SFDR at 5 MHz.
  • 85 dBc SFDR at 20 MHz.
  • 3 dB bandwidth of 320 MHz, G = +1 Fast settling to 0.01% of 16 ns Slew rate 1150 V/µs Fast overdrive recovery of 4 ns Low input voltage noise of 5 nV/√Hz 1 mV typical offset voltage Wide supply range +3 V to ±5 V Low power 90 mW on 5 V 0.1 dB gain flatness to 40 MHz Available in 8-Lead S.
