The ADL5304 is a high speed logarithmic converter with fast response and low noise over a 200 dB (1 pA to 10 mA) measurement range.

The ADL5304 provides a nominal logarithmic slope of 10 mV/dB (200 mV/decade); other values are easily configured.

Optimized for very fast response at all input currents Overall bandwidth of >4 MHz for inputs >1 µA A single positive supply of 5 V is all that is required for operation over a specified 1 pA to 3 mA input range. Dual-supply operation extends the specified input current range to 10 mA. Bandwidth: 25 kHz at input of 1 nA and 350 kHz at 10 nA 10 decades of input range: 1 pA to 10 mA Law conformance: ±0.25 dB from 100 pA to 100 µA Log ratio or fixed-intercept operation Precision voltage reference.
