AD8306AR-REEL7

Overview

The AD8306AR-REEL7 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 typical transfer slope of 20 mV/dB and an intercept of -108 dBV. The device operates on a single supply voltage between +2.7 V and +6.5 V, drawing a typical quiescent current of 16 mA. It features a small-signal bandwidth of 3.5 MHz for the RSSI output and supports usable frequencies up to 400 MHz.

Feature Summary

• Provides a complete logarithmic measure of input signal strength over a 100 dB dynamic range
• Features a programmable limiting amplifier stage with differential outputs
• Includes a CMOS-compatible control interface for rapid power-up and low-power sleep modes

Applications

• Receiver Signal Strength Indication (RSSI)
• Very wide range IF and RF power measurement
• Receivers for frequency and phase modulation
• Low cost radar and sonar signal processing

Procurement Notes

Verify the specific REEL7 suffix indicates a 7-inch tape and reel packaging format as defined in the ordering guide. Confirm that the component meets the industrial temperature range specifications of -40 °C to +85 °C. Ensure compatibility with the required 16-lead narrow body SO package dimensions for your PCB layout.

Selection Notes

Select this component when a high precision log-limiting function is required within the 5 MHz to 400 MHz frequency band. It is suitable for applications demanding stable RSSI scaling independent of temperature and supply variations. Consider the 16 mA typical supply current and the need for external components to program limiter gain and filter bandwidth.

Part Context

This part belongs to the AD8306 series of limiting-logarithmic amplifiers manufactured by Analog Devices. It is designed to replace older discrete solutions by integrating ten detectors and six amplifier stages into a single monolithic chip. The device utilizes advanced complementary bipolar processes with silicon-on-insulator isolation techniques.

Replacement Considerations

The AD8306AR-REEL is a compatible alternative offering identical electrical characteristics but packaged in a 13-inch tape and reel.
