ADA4937-2 - Dual Ultralow Distortion / Differential ADC Driver

Description

The ADA4937-1/ADA4937-2 are low noise, ultralow distortion, high speed differential amplifiers.

They are an ideal choice for driving high performance ADCs with resolutions up to 16 bits from dc to 100 MHz.

Features

  • Extremely low harmonic distortion (HD).
  • 112 dBc HD2 at 10 MHz.
  • 84 dBc HD2 at 70 MHz.
  • 77 dBc HD2 at 100 MHz.
  • 102 dBc HD3 at 10 MHz.
  • 91 dBc HD3 at 70 MHz.
  • 84 dBc HD3 at 100 MHz Low input voltage noise: 2.2 nV/√Hz High speed.
  • 3 dB bandwidth of 1.9 GHz, G = 1 Slew rate: 6000 V/μs, 25% to 75% Fast overdrive recovery of 1 ns 0.5 mV typical offset voltage Externally adjustable gain Differential-to-differential or single-ended-to-differential opera.
