ADL5310ACPZ-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 two independent channels optimized for photodiode interfacing, supporting an input current range from 3 nA to 3 mA. It features a nominal slope of 10 mV/dB (200 mV/decade) with law conformance of 0.3 dB across the specified range. The component is housed in a 24-lead LFCSP package and supports operation from -40°C to +85°C.

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
• Supports single-supply or dual-supply operation

Applications

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

Procurement Notes

Verify that the ordering suffix REEL7 corresponds to reel packaging specifications. Confirm the specific revision status against the manufacturer's latest documentation. Ensure compatibility with the required operating temperature range and supply voltage constraints before finalizing procurement decisions.

Selection Notes

Select this component when designing systems requiring wide dynamic range current-to-voltage conversion. It is suitable for applications needing precise logarithmic response over multiple decades. Consider the external resistor requirements for setting reference currents and intercept points to match specific system parameters.

Part Context

This part belongs to the ADL5310 series of dual logarithmic converters. It is designed for optical communication systems, including control circuitry for lasers, optical switches, attenuators, and amplifiers. The device serves as a compact solution for measuring gain or attenuation across optical elements.

Replacement Considerations

The ADL5310 is functionally equivalent to the dual AD8305 but offers enhanced dynamic range.
