ADA4950-2YCPZ-RL

Overview

The ADA4950-2YCPZ-RL is a dual-channel, low-power, selectable gain differential ADC driver manufactured by Analog Devices. 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 selectable differential gains of 1, 2, and 3 via internal feedback networks. Key electrical specifications include a small-signal bandwidth of 750 MHz at G=1, a slew rate of 2900 V/µs, and a typical input offset voltage of ±0.2 mV. Quiescent current consumption is approximately 9.5 mA per amplifier.

Feature Summary

• Selectable differential gains of 1, 2, and 3 configured through external connections to internal feedback networks
• Adjustable output common-mode voltage using an internal common-mode feedback loop for ADC matching
• High-speed performance with a 750 MHz small-signal bandwidth and 2900 V/µs slew rate
• Low harmonic distortion and noise characteristics suitable for high-performance data acquisition

Applications

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

Procurement Notes

Verify the specific ordering suffix YCPZ-RL against the manufacturer's official documentation to confirm package type and reel quantity. Ensure compatibility with the required PCB footprint for the 24-lead LFCSP package. Confirm that the selected component meets the necessary environmental and operational standards for the intended application before finalizing procurement.

Selection Notes

Select this component when driving high-performance ADCs requiring single-ended-to-differential or differential-to-differential conversion. Consider the adjustable output common-mode voltage feature for precise signal matching. Evaluate the power consumption requirements against the 9.5 mA per amplifier quiescent current specification. Ensure the application frequency falls within the specified bandwidth limits for optimal linearity and distortion performance.

Part Context

This part belongs to the ADA4950-x series, which are gain-selectable versions of the ADA4932-x family. Manufactured using a proprietary silicon-germanium (SiGe) complementary bipolar process, these devices achieve low distortion and noise levels at low power. The series is designed for broadband DC-coupled applications and signal processing tasks requiring high dynamic range.

Replacement Considerations

The ADA4950-1 serves as the single-channel counterpart within the same series. Designers should verify pinout compatibility and channel count requirements when considering substitutions between the single and dual-channel variants in this product family.
