ADL5310ACP-REEL7

Overview

The ADL5310ACPZ-REEL7 is a dual logarithmic converter manufactured by Analog Devices Inc. It operates within a supply voltage range of 3 V to 12 V and consumes approximately 9.5 mA of quiescent current. The device provides a 120 dB dynamic range, accepting input currents from 3 nA to 3 mA with a nominal slope of 10 mV/dB (200 mV/dec). It features two independent channels optimized for photodiode interfacing, housed in a space-efficient 24-lead LFCSP package.

Feature Summary

• Dual independent channels optimized for photodiode interfacing
• Temperature-stable logarithmic outputs with externally scalable slope
• User-configurable output buffer amplifiers for signal conditioning

Applications

• Gain and absorbance measurements
• Multichannel power monitoring
• General-purpose baseband log compression

Procurement Notes

Verify the specific suffix REEL7 indicates reel packaging when sourcing. Confirm the component matches the 24-lead LFCSP physical footprint. Ensure the manufacturer is Analog Devices Inc. Check RoHS compliance status before integration into final assemblies.

Selection Notes

Select this component for applications requiring wide dynamic range current-to-voltage conversion. It is suitable for optical communication systems where laser control or system monitoring is necessary. Consider the single-supply operation capability and the availability of user-configurable buffers for interface flexibility.

Part Context

This part belongs to the ADL5310 series of dual logarithmic converters. It serves as an enhanced alternative to previous models like the AD8305, offering increased dynamic range. The device utilizes a translinear structure to convert input current into a linear-in-dB output voltage, making it ideal for supervisory systems in fiber optics.

Replacement Considerations

The ADL5310 is functionally equivalent to the dual AD8305 but with enhanced dynamic range. Verify pin compatibility and thermal characteristics if substituting other dual-channel logarithmic amplifiers in existing designs.
