ADA4938-1 - Ultra-Low Distortion Differential ADC Driver

Datasheet Summary

Description

The ADA4938-1/ADA4938-2 are low noise, ultralow distortion, high speed differential amplifiers.

It is an ideal choice for driving high performance ADCs with resolutions up to 16 bits from dc to 27 MHz, or up to 12 bits from dc to 74 MHz.

Features

  • Extremely low harmonic distortion (HD).
  • 106 dBc HD2 @ 10 MHz.
  • 82 dBc HD2 @ 50 MHz.
  • 109 dBc HD3 @ 10 MHz.
  • 82 dBc HD3 @ 50 MHz Low input voltage noise: 2.6 nV/√Hz High speed.
  • 3 dB bandwidth of 1000 MHz, G = +1 Slew rate: 4700 V/μs 0.1 dB gain flatness to 150 MHz Fast overdrive recovery of 4 ns 1 mV typical offset voltage Externally adjustable gain Differential-to-differential or single-ended-to-differential operation Adjustable output common-mode voltage Wid.
