ADL5304ACPZ-R7

ADL5304 is a high speed logarithmic converter with fast response and low noise over a 200dB (1pA to 10mA) measurement range. The ADL5304 provides a nominal logarithmic slope of 10mV/dB(200 m V/decade ) other values are easily configured. Logarithmic intercept can be programmed over a wide range with the internal 100nA current source or externally for log ratio applications. Typical application includes high accuracy optical power measurement, wide range baseband log compression and versatile detector for high speed APC loops.
