ADA4960-1ACPZ-RL

Overview

The ADA4960-1ACPZ-RL is a high-performance, single-supply differential amplifier optimized for RF and IF applications. It features a 5 GHz bandwidth at 6 dB gain, 8700 V/µs slew rate, and programmable gain from 0 dB to 18 dB via a single resistor. The device maintains a constant 10 kΩ input impedance and includes a nominal 150 Ω output impedance. Operating on a 5 V supply with 60 mA quiescent current, it delivers low distortion (IMD3 -63 dBc at 1 GHz) and fast overdrive recovery.

Feature Summary

• Buffered inputs isolate the gain-setting resistor from signal paths, maintaining constant input impedance across all gain settings.
• Single-resistor programmable gain allows flexible configuration from 0 dB to 18 dB without affecting input matching.
• Integrated enable pin provides power-down mode with excellent input-to-output isolation when disabled.
• Output limiting protects downstream components by clamping outputs during overdrive conditions without overshoot.

Applications

• Differential ADC drivers for giga-sample analog-to-digital converters
• GBPS line drivers with pre-emphasis capabilities
• High-speed data acquisition systems
• Electronic surveillance countermeasures
• Pulse capture and conditioning circuits

Procurement Notes

Verify the specific ordering suffix matches the required reel quantity and tape-and-reel specifications. Confirm that the LFCSP package dimensions align with your PCB footprint requirements. Ensure thermal management strategies account for the junction temperature limits under maximum ambient operating conditions. Validate that the 5 V single-supply voltage range meets your system power constraints before finalizing procurement.

Selection Notes

Select this component when driving high-speed ADCs requiring low distortion and wide bandwidth. Consider the fixed 10 kΩ input impedance for source matching requirements. Evaluate the 150 Ω output impedance against load requirements to ensure proper signal integrity. Verify that the 5 V supply capability fits within your available power rails and that the thermal dissipation characteristics suit your enclosure design.

Part Context

This part belongs to Analog Devices' family of high-speed differential amplifiers designed for RF and IF processing. It utilizes a SiGe process to achieve superior speed and linearity compared to standard bipolar technologies. The 16-lead LFCSP package provides a compact solution for space-constrained designs while maintaining thermal performance through an exposed pad connection.

Replacement Considerations

Check for direct cross-reference part numbers in Analog Devices' portfolio that offer similar bandwidth and gain configurations. Verify compatibility with existing PCB footprints if substituting packages. Ensure replacement devices support the same 5 V single-supply operation and maintain comparable IMD3 performance levels at target frequencies.
