AD8337BCPZ-REEL

Overview

The AD8337BCPZ-REEL is a low noise, single-ended, linear-in-dB variable gain amplifier (VGA) from Analog Devices. It operates from DC 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 referenced to VCOM. Input voltage noise is 2.2 nV/√Hz, and input current noise is 4.8 pA/√Hz. It supports supply voltages of +5 V or ±2.5 V / ±5 V, consuming 78 mW at ±2.5 V. The component is housed in an 8-pin LFCSP package.

Feature Summary

• Utilizes X-AMP architecture for linear-in-dB gain control across the full operating range.
• Integrates a high-speed uncommitted current feedback preamplifier for flexible circuit configurations.
• Provides excellent bandwidth uniformity independent of the selected gain setting.
• Supports dual-supply operation to enable gain control of negative-going pulses.

Applications

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

Procurement Notes

Verify the specific suffix REEL against the manufacturer's ordering guide to confirm packaging type and quantity specifications. Ensure the component meets RoHS compliance requirements for the intended deployment environment. Cross-reference the datasheet revision history to validate that all electrical parameters match the design specifications before finalizing procurement orders.

Selection Notes

Select this VGA when low output-referred noise and wide bandwidth are critical for driving high-speed analog-to-digital converters. The integrated uncommitted op amp allows for additional signal conditioning within the same footprint. Consider the thermal performance of the exposed pad for optimal heat dissipation in dense PCB layouts requiring reliable long-term operation.

Part Context

This component belongs to the AD8337 series of general-purpose, low-cost, DC-coupled variable gain amplifiers manufactured by Analog Devices. The series utilizes proprietary X-AMP technology to deliver consistent performance across varying temperature conditions. It is designed as a versatile solution for applications requiring precise amplitude control without significant signal distortion.

Replacement Considerations

Consult the official datasheet ordering guide for confirmed substitute part numbers. Verify pin compatibility and electrical parameter alignment before implementing any alternative components in existing designs.
