ADA4922-1 - Differential 18-Bit ADC Driver

General Description

The ADA4922-1 is a differential driver for 16-bit to 18-bit ADCs that have differential input ranges up to ±20 V.

Configured as an easy-to-use, single-ended-to-differential amplifier, the ADA4922-1 requires no external components to drive ADCs.

Key Features

  • Single-ended-to-differential conversion Low distortion (VO, dm = 40 V p-p).
  • 99 dBc HD at 100 kHz Low differential output referred noise: 12 nV/√Hz High input impedance: 11 MΩ Fixed gain of 2 No external gain components required Low output-referred offset voltage: 1.1 mV max Low input bias current: 3.5 μA max Wide supply range 5 V to 26 V Can produce differential output signals in excess of 40 V p-p High speed 38 MHz,.
  • 3 dB bandwidth @ 0.2 V p-p differential output Fast settling t.
