ADA4960-1ACPZ-R7

Overview

The ADA4960-1ACPZ-R7 is a high-performance differential amplifier optimized for RF and IF applications, fabricated on a SiGe process. It operates from a single 5 V supply with a typical quiescent current of 60 mA. The device features buffered inputs maintaining a constant 10 kΩ differential input resistance and a nominal 150 Ω differential output impedance. Gain is programmable from 0 dB to 18 dB using a single resistor. Key electrical specifications include a -3 dB bandwidth of 5 GHz at 6 dB gain, a slew rate of 8700 V/µs, and fast settling time of 1 ns to 1%. It supports operation over an ambient temperature range of −40°C to +85°C.

Feature Summary

• Buffered inputs isolate the gain-setting resistor from signal inputs, ensuring constant input impedance across all gain settings.
• Single-resistor programmable gain allows flexible configuration from 0 dB to 18 dB.
• Fast overdrive recovery and output limiting protect downstream components without external clamping.
• User-accessible bandwidth extension feature enables optimization for line driver and channel equalization applications.

Applications

• Differential ADC drivers for giga-sample analog-to-digital converters
• GBPS line drivers with pre-emphasis
• High-speed data acquisition systems
• Electronic surveillance countermeasures
• Oscilloscopes

Procurement Notes

Verify the specific ordering suffix R7 corresponds to the reel packaging format required for your assembly line. Confirm that the LFCSP package exposed pad connection requirements align with your PCB thermal design guidelines. Ensure the component meets RoHS compliance standards applicable to your manufacturing region before finalizing procurement orders.

Selection Notes

Select this component when designing circuits requiring wideband performance up to 1 GHz with low distortion characteristics. It is suitable for driving mixers, SAW filters, or pin diode attenuators where adjustable gain is necessary. Consider the 150 Ω output impedance for matching requirements and verify that the 5 V single-supply constraint fits within your system power architecture.
