ADA4950-1YCPZ-RL

Overview

The ADA4950-1YCPZ-RL is a single-channel, low-power, selectable gain differential amplifier manufactured by Analog Devices Inc. It operates within a supply voltage range of +3 V to ±5 V and features an operating temperature range from −40°C to +105°C. The device provides selectable differential gains of 1, 2, and 3 through internal feedback networks connected externally. Key performance metrics include a small-signal bandwidth of 750 MHz at G=1, a slew rate of 2900 V/µs, and a typical input offset voltage of ±0.2 mV. It consumes 9.5 mA per amplifier and offers low output voltage noise of 9.2 nV/√Hz.

Feature Summary

• Selectable differential gains of 1, 2, and 3 via external connection to internal feedback networks
• Adjustable output common-mode voltage using an internal common-mode feedback loop
• Low power consumption with high-speed dynamic performance suitable for data acquisition

Applications

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

Procurement Notes

Verify the specific ordering suffix YCPZ-RL against the manufacturer's current documentation to confirm package type and reel specifications. Ensure compatibility with the intended PCB layout requirements for the LFCSP package. Confirm that the selected gain configuration matches the application needs before finalizing procurement.

Selection Notes

Select this component when driving high-performance ADCs requiring single-ended-to-differential or differential-to-differential conversion. Consider its low power and high speed characteristics for applications needing adjustable output common-mode voltage. Evaluate the available gain options (1, 2, and 3) to determine if the internal feedback network meets the closed-loop gain requirements without external resistors.

Part Context

The ADA4950-1 is part of the ADA4950-x family, which includes the dual-channel ADA4950-2. These devices are gain-selectable versions of the ADA4932 series, fabricated using a proprietary silicon-germanium complementary bipolar process. This technology enables low distortion and noise levels at low power consumption, making them suitable for various signal processing applications.

Replacement Considerations

The ADA4932-1 serves as a related predecessor in the same family. Verify pinout compatibility and electrical parameter alignment before substitution. Consult official documentation for any differences in gain configurations or package types.
