ADPD2210 - Low Power Current Amplifier

Datasheet Summary

Description

The ADPD2210 is a low noise current amplifier designed to allow the use of smaller photodiodes by amplifying sensor signal currents by a factor of 24 while adding minimal noise.

Features

  • Ultralow noise, low power current amplifier 80 fA/√Hz (typical) noise floor 140 μA (typical) of supply current when active (EE = 0 μW/cm2) 100 nA (typical) of supply current in standby Flexible output configuration Optimized for pulsed systems Nominal linear output: 240 μA Space-saving 2 mm × 2 mm LFCSP package.
