ADA4930-1YCPZ-R7

Overview

The ADA4930-1YCPZ-R7 is a single-channel ultralow noise differential amplifier in a 16-lead LFCSP package. It operates on a single 3.3 V or 5 V supply with a quiescent current of approximately 34 mA per amplifier. Key electrical parameters include a small-signal bandwidth of 1.35 GHz, a slew rate of 3400 V/μs, and an input voltage noise density of 1.2 nV/√Hz at 5 V operation. The device features adjustable output common-mode voltage via the VOCM pin and supports gains set by external feedback resistors.

Feature Summary

• Ultralow input voltage noise density for high-fidelity signal processing
• Extremely low harmonic distortion with internal common-mode feedback for exceptional output balance
• High-speed performance with wide bandwidth and fast overdrive recovery
• Flexible configuration supporting differential-to-differential or single-ended-to-differential operation

Applications

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

Procurement Notes

Verify the specific ordering suffix R7 corresponds to reel packaging when sourcing. Confirm the component matches the 16-lead LFCSP physical footprint and pinout defined in the datasheet. Ensure the supply voltage requirements align with the 3.3 V or 5 V operational specifications provided in the official documentation.

Selection Notes

Select this component for applications requiring high speed and low noise in a compact surface-mount package. The single-channel architecture suits designs needing one differential driver. Consider the 1.35 GHz bandwidth and 3400 V/μs slew rate for high-frequency signal integrity. Verify that the required gain settings can be achieved with available external resistor values within the specified input resistance limits.

Part Context

This part belongs to the ADA4930 family of ultralow noise drivers designed specifically for low voltage ADCs. The -1 suffix indicates a single-channel configuration, distinguishing it from the dual-channel ADA4930-2. Manufactured using a silicon-germanium complementary bipolar process, the device optimizes PCB layout to minimize distortion while maintaining high dynamic performance.

Replacement Considerations

The ADA4930-2 serves as the dual-channel counterpart within the same family. Designers requiring two channels may consider this alternative if the board space allows for the 24-lead LFCSP package. No other direct substitutes are confirmed in the provided documentation.

FAQ

How is the output common-mode voltage controlled?

The output common-mode voltage is adjusted by applying a voltage to the VOCM pin. An internal common-mode feedback loop forces the output common-mode level to match the voltage applied to this input.

What is the typical input offset voltage?

The typical input offset voltage is 0.5 mV, with a maximum specified drift of 2.75 μV/°C across the operating temperature range.

Does the device support power-down functionality?

Yes, the ADA4930-1 includes a Power-Down (PD) pin. Driving this pin low disables the amplifier, reducing the quiescent current significantly compared to the enabled state.
