Overview

The LOG200 evaluation module (EVM) is a development platform for evaluating the LOG200, which is a precision, high-speed logarithmic amplifier with integrated photodiode bias and dark-current correction. LOG200 is optimized for current measurements across 160 dB of dynamic range with unparalleled accuracy.

Features
  • High-accuracy logarithmic transfer function; LOG200 ratio internally set to 250 mV/decade of current-to-voltage conversion
  • Integrated photodiode bias and dark-current correction adaptive-biasing circuit
  • Footprint for photosensor connection
  • Precision 1-μA current reference
  • Precision 1.65-V and 2.5-V voltage references
  • Single-supply (5 V) or dual-supply (±5 V) operation
