ADA4937-2YCPZ-RL

Overview

The ADA4937-2YCPZ-RL is a dual-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 3.3 V and 5 V. Key electrical parameters include a small-signal bandwidth of 1.9 GHz at unity gain, a slew rate of 6000 V/µs, and an input voltage noise of 2.2 nV/√Hz. The device features adjustable output common-mode voltage and externally adjustable gain via a four-resistor feedback network.

Feature Summary

• Ultralow harmonic distortion performance suitable for high-resolution data acquisition
• Internal common-mode feedback loop ensures exceptional output balance
• Adjustable output common-mode voltage matches ADC input requirements
• Fast overdrive recovery time minimizes transient settling delays

Applications

• Driving high-performance ADCs
• Single-ended-to-differential conversion
• IF and baseband gain blocks
• Differential buffers
• Line drivers

Procurement Notes

Verify the specific ordering suffix RL indicates reel packaging configuration. Confirm the component meets RoHS compliance standards required for your assembly process. Ensure the LFCSP package thermal management aligns with your PCB layout capabilities. Cross-reference the datasheet revision F specifications against your design requirements before finalizing procurement.

Selection Notes

Select this component when driving ADCs requiring low noise and high linearity. The dual-channel architecture supports independent signal processing paths. Verify that the external feedback resistor network allows for the desired closed-loop gain configuration. Ensure the operating temperature range of -40°C to +105°C fits within your system's environmental constraints.

Part Context

This part belongs to the ADA4937 family of differential amplifiers manufactured by Analog Devices Inc. using a proprietary silicon-germanium complementary bipolar process. The ADA4937-2 variant specifically provides two independent channels in a 24-lead, 4 mm × 4 mm lead frame chip scale package (LFCSP).

Replacement Considerations

The ADA4937-1 serves as the single-channel counterpart within the same family. Designers should verify pinout compatibility and channel count requirements when considering substitutes from other manufacturers.
