ADA4950-2YCPZ-R7

Overview

The ADA4950-2YCPZ-R7 is a dual-channel, low-power, selectable gain differential ADC driver manufactured by Analog Devices Inc. It operates on supply voltages ranging from +3 V to ±5 V and features an operating temperature range of −40°C to +105°C. The device provides a small-signal bandwidth of 750 MHz at G = 1, with a slew rate of 2900 V/µs and a fast 0.1% settling time of 9 ns. It consumes 9.5 mA per amplifier and offers selectable differential gains of 1, 2, and 3.

Feature Summary

• Selectable differential gains of 1, 2, and 3 via internal feedback networks
• Adjustable output common-mode voltage using an internal feedback loop
• Low harmonic distortion with suppression of even-order products
• Power-down capability for reduced current consumption

Applications

• ADC drivers
• Single-ended-to-differential converters
• IF and baseband gain blocks
• Differential buffers
• Line drivers

Procurement Notes

Verify the specific ordering suffix R7 indicates reel packaging when sourcing this component. Confirm that the YCPZ designation corresponds to the 24-lead LFCSP package type. Ensure compatibility with the required supply voltage range and temperature specifications before finalizing procurement decisions.

Selection Notes

Select the ADA4950-2YCPZ-R7 for applications requiring dual-channel differential signal processing with adjustable gain. Consider its low power consumption and high-speed performance for driving high-performance ADCs. Evaluate the need for single-ended-to-differential or differential-to-differential conversion capabilities in your system design.

Part Context

This component belongs to the ADA4950-x series, which includes the single-channel ADA4950-1 and the dual-channel ADA4950-2. These devices are gain-selectable versions of the ADA4932-1/ADA4932-2, fabricated using Analog Devices' proprietary silicon-germanium (SiGe) complementary bipolar process for low distortion and noise.

Replacement Considerations

The ADA4950-1 serves as the single-channel counterpart within the same family. For direct replacement, verify pinout compatibility and ensure the application does not require the dual-channel configuration provided by the ADA4950-2.
