ADA4930-1 - Ultralow Noise Drivers

General Description

The ADA4930-1/ADA4930-2 are very low noise, low distortion, high speed differential amplifiers.

They are an ideal choice for driving 1.8 V high performance ADCs with resolutions up to 14 bits from dc to 70 MHz.

Key Features

  • Low input voltage noise: 1.2 nV/√Hz Low common-mode output: 0.9 V on single supply Extremely low harmonic distortion.
  • 104 dBc HD2 at 10 MHz.
  • 79 dBc HD2 at 70 MHz.
  • 73 dBc HD2 at 100 MHz.
  • 101 dBc HD3 at 10 MHz.
  • 82 dBc HD3 at 70 MHz.
  • 75 dBc HD3 at 100 MHz High speed.
  • 3 dB bandwidth of 1.35 GHz, G = 1 Slew rate: 3400 V/μs, 25% to 75% 0.1 dB gain flatness to 380 MHz Fast overdrive recovery of 1.5 ns 0.5 mV typical offset voltage Externally adjus.
