ADA4950-1YCPZ-R7

Overview

The ADA4950-1YCPZ-R7 is a low-power, selectable gain differential ADC driver manufactured by Analog Devices Inc. It operates within a supply voltage range of +3 V to ±5 V and features a quiescent current of 9.5 mA per amplifier. The device provides a small-signal bandwidth of 750 MHz at G = 1 with a slew rate of 2900 V/µs. It supports differential gains of 1, 2, and 3 via internal feedback networks. The component is housed in a 16-lead LFCSP package and is rated for operation between −40°C and +105°C.

Feature Summary

• Selectable differential gains of 1, 2, and 3 using on-chip feedback resistors
• Adjustable output common-mode voltage via an internal feedback loop
• Low harmonic distortion with suppression of even-order products
• Single-ended-to-differential or differential-to-differential conversion capability

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-R7 against official documentation to confirm reel packaging and tape specifications. Confirm that the R7 designation aligns with the required quantity per reel for your production line. Ensure compatibility with standard surface-mount reflow profiles for the LFCSP package type before initiating procurement.

Selection Notes

Select this component when driving high-performance ADCs requiring low power consumption and adjustable gain configurations. The SiGe complementary bipolar process ensures low noise and distortion suitable for data acquisition systems. Evaluate the input common-mode range shift and output balance requirements to ensure optimal signal integrity in single-supply or dual-supply environments.

Part Context

This part belongs to the ADA4950-x series, which are gain-selectable versions of the ADA4932-x family. Manufactured using a proprietary silicon-germanium (SiGe) complementary bipolar process, these devices offer optimized pinouts for PCB layout to minimize distortion. The series is designed for applications demanding high dynamic performance and low offset voltages.

FAQ

How is the closed-loop gain configured?

Differential gains of 1, 2, and 3 are realized by connecting external components to the internal feedback networks associated with the positive and negative input pins.

What is the function of the PD pin?

The Power-Down (PD) pin allows the device to be disabled to reduce power consumption. It turns off within 600 ns and turns on within approximately 28 ns.
