ADA4930-1SCPZ-EPR2

Overview

The ADA4930-1SCPZ-EPR2 is an enhanced product, ultralow noise differential amplifier designed for driving high-performance analog-to-digital converters (ADCs). It operates on a single 3.3 V or 5 V supply and features a 16-lead LFCSP package. Key electrical parameters include a small-signal bandwidth of 1350 MHz at 5 V, a slew rate of 3400 V/µs, and an input voltage noise of 1.2 nV/√Hz. The device supports an operating temperature range from −55°C to +105°C.

Feature Summary

• Supports defense and aerospace applications under the AQEC standard with controlled manufacturing baselines.
• Features adjustable output common-mode voltage to match ADC inputs for maximum dynamic range.
• Utilizes internal common-mode feedback loops to provide exceptional output balance and suppress even-order harmonic distortion.
• Fabricated using proprietary silicon-germanium complementary bipolar process for low distortion performance.

Applications

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

Procurement Notes

Verify that the specific ordering suffix EPR2 corresponds to the required reel quantity of 250 units as listed in the official Analog Devices ordering guide. Confirm that the enhanced product designation ensures compliance with the specified extended temperature range and controlled fabrication site requirements for your application environment.

Selection Notes

Select this component when driving 1.8 V high-performance ADCs with resolutions up to 14 bits. It is suitable for applications requiring dc to 70 MHz operation. Ensure the design accommodates the 3 mm × 3 mm 16-lead LFCSP footprint and utilizes the exposed paddle for thermal management on a conductive PCB plane.

Part Context

This part belongs to the ADA4930-EP enhanced product family, which adheres to strict quality standards for defense and aerospace use. It shares core specifications with the standard ADA4930-1 but offers guaranteed manufacturing origins and enhanced change notification protocols. The device is a single-channel differential amplifier within the broader Analog Devices signal chain portfolio.

FAQ

What is the typical input offset voltage for the ADA4930-1SCPZ-EPR2?

The typical input offset voltage is 0.5 mV at 25°C and 0.15 mV at 5 V operation, with a maximum drift of 2.75 µV/°C across the temperature range.

How does the power-down feature function?

The device includes a power-down (PD) pin. Pulling the PD pin low disables the amplifier, reducing quiescent current significantly. The turn-off time is 1 µs, and the turn-on time is 12 ns.
