AD8306ARZ-RL7

Overview

The AD8306ARZ-RL7 is a fully calibrated logarithmic amplifier and limiter from Analog Devices, housed in a 16-lead SOIC package. It provides a 100 dB dynamic range with a stable RSSI scaling of 20 mV/dB slope and –95 dBm intercept. The device features a 400 MHz bandwidth, 90 dB overall gain, and operates on a single supply voltage ranging from +2.7 V to +6.5 V at a typical current of 16 mA. It includes differential limiter outputs and a CMOS-compatible enable interface.

Feature Summary

• Provides accurate logarithmic measurement over a 100 dB dynamic range with laser-trimmed linearity.
• Features a fully differential input stage and programmable hard-limiter output for signal processing.
• Includes a CMOS-compatible control interface for rapid power-up and low-current standby modes.

Applications

• Receiver Signal Strength Indication (RSSI)
• Very Wide Range IF and RF Power Measurement
• Receivers for Frequency and Phase Modulation

Procurement Notes

Verify the specific suffix RL7 against the official datasheet ordering guide to confirm tape-and-reel packaging specifications. Ensure the industrial temperature range (-40°C to +85°C) matches the application requirements. Cross-reference the manufacturer part number with authorized distributors to confirm current availability status.

Selection Notes

Select this component when a high-precision, wide-dynamic-range logarithmic response is required without external calibration. Consider the 400 MHz bandwidth and 100 dB range for applications needing precise amplitude monitoring. Evaluate the single-supply operation and low quiescent current for power-constrained designs.

Part Context

This part belongs to the AD8306 series of limiting-logarithmic amplifiers. It is designed for applications requiring both amplitude detection and signal limiting within a single integrated circuit. The device utilizes an advanced complementary bipolar process with silicon-on-insulator isolation techniques for high performance.
