AD8337BCPZ-R2

Overview

The AD8337BCPZ-R2 is a low noise, single-ended, linear-in-dB, general-purpose variable gain amplifier (VGA) from Analog Devices. It operates at frequencies up to 100 MHz with a −3 dB bandwidth of 280 MHz. The device features a nominal gain range of 0 dB to 24 dB and a gain scaling factor of 19.7 dB/V. It includes a high-speed uncommitted op amp input and supports supply voltages of +5 V or ±2.5 V/±5 V. Power consumption is 78 mW with ±2.5 V supplies.

Feature Summary

• Linear-in-dB gain control with excellent bandwidth uniformity across the entire gain range
• Low output-referred noise suitable for driving high-speed analog-to-digital converters
• Integrated high-speed uncommitted current feedback operational amplifier input

Applications

• Gain trim applications
• PET scanners
• High performance AGC systems
• Industrial and medical ultrasound
• Radar receivers

Procurement Notes
