LTC6563DICE - 4-Channel Transimpedance Amplifier

Description

The LTC6563DICE is a low noise, 4-channel transimpedance amplifier (TIA) with 600 MHz bandwidth.

The low noise, wide linear range, and low power dissipation of the TIA are ideal for light detecting and ranging (LIDAR) receivers using avalanche photodiodes and photodiodes.

Features

  • 600 MHz.
  • 3 dB bandwidth with 0.5 pF input capacitance.
  • Differential output with up to 2 V p-p swing into 100 Ω differential load.
  • Built-in high-speed ADC driver with output mux.
  • Selectable 22.2 kΩ, 16.7 kΩ, 11.1 kΩ, or 5.55 kΩ transimpe- dance gain.
  • 1.8 pA/√Hz to 3.7 pA/√Hz input current noise density 100 MHz to 600 MHz (0.5 pF).
  • 65 nA RMS integrated input-referred current noise over 600 MHz (0.5 pF).
  • Large linear input current range 0 µA to 90 µA.
