AD8330 - Variable Gain Amplifier

General Description

The AD8330 is a wideband variable gain amplifier for applications requiring a fully differential signal path, low noise, well-defined gain, and moderately low distortion, from dc to 150 MHz.

Key Features

  • Fully differential signal path, also used with single-sided signals Inputs from 0.3 mV to 1 V rms, rail-to-rail outputs Differential RIN = 1 kΩ; ROUT (each output) 75 Ω Automatic offset compensation (optional) Linear-in-dB and linear-in-magnitude gain modes 0 dB to 50 dB, for 0 V < VDBS < 1.5 V (30 mV/dB) Inverted gain mode: 50 dB to 0 dB at.
  • 30 mV/dB ×0.03 to ×10 nominal gain for 15 mV < VMAG < 5 V Constant bandwidth: 150 MHz at all gains Low noise: 5 nV/√Hz typical at maximum gain Low.
