AD8260 - High Current Driver Amplifier and Digital VGA/Preamplifier

Description

The AD8260 includes a high current driver, usable as a transmitter, and a low noise digitally programmable variable gain amplifier (DGA), useable as a receiver.

The receiver section consists of a single-ended input preamplifier, and linear-in-dB, differential-output DGA.

Features

  • High current driver Differential input.
  • direct drive from DAC Preset gain: 1.5×.
  • 3 dB bandwidth: 195 MHz Large output drive: >±300 mA VGA/preamplifier Low noise Voltage noise: 2.4 nV/√Hz Current noise: 5 pA/√Hz.
  • 3 dB bandwidth: 230 MHz Gain range: 30 dB in 3 dB steps.
  • 6 dB to +24 dB (for preamplifier gain of 6 dB) Single-ended preamplifier input and differential VGA output Supplies: 3.3 V to 10 V (with VMID enabled) ±3.3 V to ±5 V (with VMID disabled) Power: 93 mW.
