ADA4930-1SCPZ-EPR7

Overview

The ADA4930-1SCPZ-EPR7 is a single-channel, ultralow noise differential amplifier designed for driving low-voltage analog-to-digital converters (ADCs). It operates on a single supply of 3.3 V or 5 V and features a 16-LFCSP-VQ(3x3) package. Key electrical parameters include a small-signal bandwidth of 1.35 GHz at G=1, a slew rate of 3400 V/µs, and an input voltage noise of 1.2 nV/√Hz. The device offers adjustable output common-mode voltage, extremely low harmonic distortion, and fast overdrive recovery.

Feature Summary

• Ultralow input voltage noise of 1.2 nV/√Hz for high signal integrity
• Extremely low harmonic distortion with internal common-mode feedback loop
• High-speed performance with 1.35 GHz bandwidth and 3400 V/µs slew rate
• Adjustable output common-mode voltage to match ADC inputs

Applications

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

Procurement Notes

Verify the specific EPR7 suffix against the manufacturer's current ordering guide to confirm environmental compliance and packaging details. Ensure the 16-LFCSP-VQ(3x3) package dimensions align with your PCB footprint design. Confirm that the operating temperature range of −40°C to +105°C meets your system requirements. Cross-reference the datasheet revision B specifications for accurate electrical limits.

Selection Notes

Select this component when driving 1.8 V high-performance ADCs with resolutions up to 14 bits from DC to 70 MHz. It is suitable for applications requiring single-supply operation at 3.3 V or 5 V. Consider the 16-LFCSP-VQ(3x3) package for space-constrained designs. Evaluate the need for adjustable output common-mode voltage and low distortion characteristics relative to other differential amplifiers in the portfolio.

FAQ

How is the output common-mode voltage controlled?

The output common-mode voltage is controlled by the internal common-mode feedback loop, which forces the output common-mode level to equal the voltage applied to the VOCM pin.

What is the typical input offset voltage?

The typical input offset voltage is 0.5 mV.
