ADA4891-3 - Rail-to-Rail Amplifiers

This page provides the datasheet information for the ADA4891-3, a member of the ADA4891-4 Rail-to-Rail Amplifiers family.

Description

The ADA4891-1 (single), ADA4891-2 (dual), ADA4891-3 (triple), and ADA4891-4 (quad) are CMOS, high speed amplifiers that offer high performance at a low cost.

The amplifiers feature true single-supply capability, with an input voltage range that extends 300 mV below the negative rail.

Features

  • High speed and fast settling.
  • 3 dB bandwidth: 220 MHz (G = +1) Slew rate: 170 V/μs Settling time to 0.1%: 28 ns Video specifications (G = +2, RL = 150 Ω) 0.1 dB gain flatness: 25 MHz Differential gain error: 0.05% Differential phase error: 0.25° Single-supply operation Wide supply range: 2.7 V to 5.5 V Output swings to within 50 mV of supply rails Low distortion: 79 dBc SFDR at 1 MHz Linear output current: 125 mA at.
  • 40 dBc Low power: 4.4 mA per amplifier www. DataSheet4U. com CO.
