ADL5561ACPZ-R7

Overview

The ADL5561ACPZ-R7 is a high-performance differential amplifier optimized for RF and IF applications, fabricated using Analog Devices' high-speed SiGe process. It operates on a single 3 V to 3.6 V supply with a typical quiescent current of 40 mA. The device features pin-strappable gain settings of 6 dB, 12 dB, and 15.5 dB, providing a -3 dB bandwidth up to 2.9 GHz at the minimum gain setting. It offers low noise spectral density of 2.1 nV/√Hz and excellent broadband distortion performance, making it suitable for driving high-speed ADCs.

Feature Summary

• Pin-strappable gain adjustment provides selectable amplification levels without external resistors.
• Ultra-low noise input stage ensures high signal fidelity in wideband applications.
• Integrated enable control allows power-down mode with significantly reduced current consumption.
• Optimized for fast settling time and overdrive recovery to support high-speed data conversion.

Applications

• Differential ADC drivers
• Single-ended-to-differential conversion
• RF/IF gain blocks
• SAW filter interfacing

Procurement Notes

Verify the specific package marking and date code against the manufacturer's latest datasheet revision G documentation. Confirm that the R7 suffix corresponds to the reel packaging format required for automated assembly processes. Ensure compatibility with the intended operating temperature range of −40°C to +85°C before finalizing procurement specifications.

Selection Notes

Select this component when designing circuits requiring wideband differential amplification with minimal external gain-setting components. Consider the 3.3 V nominal supply requirement and the 40 mA quiescent current draw during power budgeting. Evaluate the specific gain configuration needed, as input strapping determines both the amplification factor and the corresponding input impedance matching requirements.
