ADA4950-2YCPZ-R2

Overview

The ADA4950-2YCPZ-R2 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 a quiescent current of 9.5 mA per amplifier. The device provides a -3 dB small-signal bandwidth of 750 MHz at G=1 and achieves a fast 0.1% settling time of 9 ns. It offers selectable differential gains of 1, 2, and 3, with an adjustable output common-mode voltage via an internal feedback loop. Packaged in a 24-lead LFCSP (4 mm × 4 mm), it supports operation over a temperature range of −40°C to +105°C.

Feature Summary

• Selectable differential gains of 1, 2, and 3 using internal feedback networks
• Adjustable output common-mode voltage for matching ADC inputs
• Low power consumption with 9.5 mA quiescent current per amplifier
• High-speed performance including 750 MHz bandwidth and 2900 V/µs slew rate

Applications

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

Procurement Notes

Verify the specific ordering suffix R2 indicates tape and reel packaging configuration. Confirm the component matches the 24-lead LFCSP package dimensions and pinout for the dual-channel variant. Ensure the manufacturer is Analog Devices Inc. and that the part meets the specified operating temperature range of −40°C to +105°C before integration.

Selection Notes

Select this component when driving high-performance ADCs requiring single-ended-to-differential or differential-to-differential conversion. It is suitable for applications needing adjustable output common-mode voltage and low harmonic distortion. Consider the 24-lead LFCSP package size and thermal characteristics for PCB layout constraints.

Part Context

The ADA4950-2 is the dual-channel version of the ADA4950-1, fabricated using Analog Devices' proprietary silicon-germanium complementary bipolar process. This technology enables low distortion and noise at low power levels. The device is designed to facilitate PCB layout optimization and minimize distortion through its optimized pinout arrangement.

Replacement Considerations

The ADA4950-2 serves as a gain-selectable alternative to the ADA4932-2. Verify compatibility regarding gain configurations and package dimensions when substituting.
