ADA4930-2YCPZ-R7

Overview

The ADA4930-2YCPZ-R7 is a dual-channel, ultralow noise differential amplifier designed for driving low-voltage analog-to-digital converters. It operates on a single 3.3 V or 5 V supply and features a 1.35 GHz small-signal bandwidth with a 3400 V/μs slew rate. The device delivers extremely low harmonic distortion, achieving -104 dBc HD2 at 10 MHz under 5 V operation. It includes an adjustable output common-mode voltage and a power-down pin, housed in a 24-lead LFCSP package.

Feature Summary

• Ultralow input voltage noise of 1.2 nV/√Hz
• Extremely low harmonic distortion performance
• Internal common-mode feedback loop for exceptional output balance
• Adjustable output common-mode voltage

Applications

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

Procurement Notes

Verify the specific ordering suffix to confirm the reel quantity and tape specifications required for your assembly line. Confirm that the component meets RoHS3 compliance standards. Ensure the operating temperature range aligns with your system's thermal requirements. Check for any recent product change notices regarding manufacturing sites or materials.

Selection Notes

Select this component when driving high-performance ADCs requiring resolutions up to 14 bits from DC to 70 MHz. The internal common-mode feedback simplifies layout by eliminating the need for tightly matched external components for balance. Consider the 24-lead LFCSP package size for space-constrained designs requiring dual channels.

Part Context

This part belongs to the ADA4930 family of differential amplifiers fabricated using Analog Devices' proprietary silicon-germanium process. The dual-channel variant provides two independent amplifier circuits within a single compact package, facilitating balanced signal processing chains.

Replacement Considerations

The ADA4930-1YCPZ-R7 serves as the single-channel equivalent within the same family. Other members of the ADA4930 series may offer different channel counts or package options while maintaining similar electrical characteristics.
