ADA4939-1YCPZ-R7

Overview

The ADA4939-1YCPZ-R7 is a single-channel, ultralow distortion differential amplifier designed for driving high-performance analog-to-digital converters (ADCs) with resolutions up to 16 bits. It operates on a single supply between 3.0 V and 5.25 V. The device features a small-signal bandwidth of 1400 MHz and a slew rate of 6800 V/µs at 5 V operation. It provides extremely low harmonic distortion, achieving -102 dBc HD2 at 10 MHz. The input voltage noise is 2.3 nV/√Hz, and the typical offset voltage is ±0.5 mV. It is housed in a 16-lead LFCSP package.

Feature Summary

• Extremely low harmonic distortion performance suitable for high-resolution data acquisition systems
• Internal common-mode feedback loop ensures exceptional output balance and even-order harmonic suppression
• Fast overdrive recovery time of less than 1 nanosecond for rapid signal transitions
• User-adjustable output common-mode voltage via an internal feedback mechanism

Applications

• ADC drivers for high-speed data acquisition
• Single-ended-to-differential signal conversion
• Intermediate frequency (IF) and baseband gain blocks
• Differential buffers and line drivers

Procurement Notes

Verify that the ordering suffix matches the required reel quantity and tape specifications. Confirm the temperature range and package type align with the design requirements. Ensure the component is sourced from authorized distributors to guarantee authenticity and traceability. Check for any specific handling instructions related to moisture sensitivity levels.

Selection Notes

Select this component when ultralow distortion and high speed are critical for ADC driving applications. It is suitable for designs requiring adjustable output common-mode levels and fast recovery times. Consider the power supply range and thermal dissipation capabilities during layout. Verify that the external resistor network supports the desired closed-loop gain stability.

Part Context

This part belongs to the ADA4939 family of differential amplifiers manufactured by Analog Devices. It is the single-channel variant of the ADA4939 series, distinguished by its 16-lead LFCSP package. The dual-channel version is available as the ADA4939-2. These devices utilize a proprietary silicon-germanium process to achieve high performance.

Replacement Considerations

The ADA4939-2 serves as the dual-channel alternative within the same family. Other Ultralow Distortion Diff ADC Driver models may be considered if pin compatibility or channel count differs.
