Datasheet Summary

Description

The AD8331/AD8332/AD8334 are single-, dual-, and quadchannel, ultralow noise linear-in-dB, variable gain amplifiers (VGAs).

Features

  • Ultralow noise preamplifier (preamp) Voltage noise = 0.74 nV/√Hz Current noise = 2.5 pA/√Hz 3 dB bandwidth AD8331: 120 MHz AD8332, AD8334: 100 MHz Low power AD8331: 125 mW/channel AD8332, AD8334: 145 mW/channel Wide gain range with programmable postamp.
  • 4.5 dB to +43.5 dB in LO gain mode 7.5 dB to 55.5 dB in HI gain mode Low output-referred noise: 48 nV/√Hz typical Active input impedance matching Optimized for 10-bit/12-bit ADCs Selectable output clamping level Single 5 V supply operatio.
