Descriptions:

The LT5581IDDB#TRPBF is a high-linearity, wide dynamic range RF power detector designed for applications requiring accurate signal strength measurement. It provides a linear-in-dB output voltage proportional to the input RF power, making it suitable for automatic gain control (AGC), power monitoring, and signal strength indication in wireless communication systems.

Features:

• Wide Frequency Range: Operates from 10 MHz to 6 GHz.
• High Dynamic Range: Detects signals from -34 dBm to +10 dBm.
• Low Power Consumption: 9.5 mA typical supply current.
• Linear-in-dB Response: Output voltage scales logarithmically with input power.
• Single Supply Operation: Works from 2.7 V to 5.25 V.
• Temperature Stable: Maintains accuracy over temperature variations.
• Small Footprint: DFN-8 package (3mm x 3mm) for space-constrained applications.
