ADA4930-1SCPZ-EPRL

Overview

The ADA4930-1SCPZ-EPR7 is a single-channel, ultralow noise differential amplifier manufactured by Analog Devices Inc. It operates on a single supply of 3.3 V or 5 V and is housed in a 16-lead LFCSP-VQ (3x3 mm) 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 density of 1.2 nV/√Hz. The device features an adjustable output common-mode voltage, low harmonic distortion, and fast overdrive recovery.

Feature Summary

• Ultralow input voltage noise for high-fidelity signal processing
• Internal common-mode feedback loop ensures exceptional output balance
• Externally adjustable gain via simple four-resistor feedback network
• Fast overdrive recovery time for rapid signal restoration

Applications

• ADC drivers for high-performance analog-to-digital converters
• Single-ended-to-differential converters
• IF and baseband gain blocks
• Differential buffers
• Line drivers

Procurement Notes

Verify the specific suffix EPR7 against the manufacturer's current ordering guide to confirm tape-and-reel packaging specifications and lot traceability. Ensure the component matches the 16-LFCSP-VQ (3x3 mm) footprint requirements for your PCB layout. Cross-reference the datasheet revision to confirm operating temperature ranges and absolute maximum ratings align with your system design constraints.

Selection Notes

Select this component when driving low-voltage ADCs requiring minimal noise contribution and high linearity. The single-channel configuration suits applications needing one differential output pair. Consider the 3.3 V or 5 V supply compatibility and the need for external resistors to set gain. Evaluate thermal dissipation limits based on the 98 °C/W junction-to-ambient resistance for proper heat sinking strategies.

Part Context

This part belongs to the ADA4930 family of ultralow noise drivers designed for low-voltage ADCs. The ADA4930-1 variant provides a single channel, whereas the ADA4930-2 offers dual channels in a larger 24-lead package. Both utilize proprietary SiGe complementary bipolar processes to achieve superior dynamic performance and low distortion characteristics suitable for precision data acquisition systems.

Replacement Considerations

The ADA4930-2YCPZ-R2 serves as a dual-channel alternative within the same family but requires a different 24-lead footprint. No direct single-channel pin-compatible replacements are explicitly confirmed in the provided documentation.
