Typical Applications
ADA4950-1YCPZ-RL7 is suitable for 6 applications: High-Speed ADC Driver, Medical Ultrasound, Communications Receivers, Test and Measurement, Industrial Data Acquisition, Automotive Radar.
High-Speed ADC Driver
The ADA4950-1YCPZ-RL7 is ideal for driving high-speed ADCs in communications and instrumentation. Its selectable gain (1, 2, 3) allows matching to various ADC input ranges without external resistors. The low noise (3.5 nV/βHz) and high bandwidth (1.6 GHz) ensure minimal signal degradation. The adjustable output common-mode (VOCM) simplifies direct interface to ADC inputs, improving overall system performance.
Recommended
Medical Ultrasound
In medical ultrasound systems, the ADA4950-1YCPZ-RL7 drives ADCs in the receive path, converting the echo signals from transducers. Its low noise and high linearity preserve the weak signals, while the selectable gain accommodates varying signal amplitudes. The low power consumption is crucial for portable and multi-channel systems. The small LFCSP package saves board space in dense probe designs.
Recommended
Communications Receivers
The ADA4950-1YCPZ-RL7 is used in communications receivers to drive ADCs in IF or baseband stages. Its high bandwidth and SFDR (-80 dBc at 10 MHz) ensure that the signal integrity is maintained for digital demodulation. The selectable gain allows optimization for different signal levels, and the differential output reduces common-mode noise. It is suitable for both single-ended and differential input sources.
Recommended
Test and Measurement
In test equipment such as oscilloscopes and spectrum analyzers, the ADA4950-1YCPZ-RL7 provides the interface between the analog front-end and the ADC. Its wide bandwidth and fast slew rate (2900 V/Β΅s) enable accurate capture of high-frequency signals. The selectable gain allows the user to adjust sensitivity without changing hardware. The low distortion ensures precise measurements.
Recommended
Industrial Data Acquisition
The ADA4950-1YCPZ-RL7 is used in industrial data acquisition systems to condition sensor signals before ADC conversion. Its differential output rejects common-mode noise from long cable runs. The selectable gain allows adaptation to various sensor outputs. The wide supply range (3.3V to 5V) and low power make it suitable for field instruments. The small package is ideal for space-constrained modules.
Recommended
Automotive Radar
In automotive radar systems, the ADA4950-1YCPZ-RL7 drives ADCs that digitize the IF signals from radar transceivers. Its high bandwidth and low noise are essential for detecting small objects. The selectable gain allows dynamic range optimization. The device operates over the automotive temperature range (-40Β°C to +125Β°C) and is available in a compact package for radar modules.

Key Differentiators
- Integrated gain resistors (vs ADA4932-1YCPZ-R7)
- Selectable gain without external components (vs THS4509RGTR)
- Lower power consumption (vs THS4509RGTR)
Design Notes
Ensure proper power supply decoupling. Place 0.1 Β΅F and 10 Β΅F capacitors as close as possible to the V+ and V- pins. The ADA4950-1 operates from 3.3V to 5V single supply or Β±5V dual. The quiescent current is 5.5 mA, so power dissipation is low, but decoupling is critical for high-frequency performance.
For optimal performance, use a ground plane and keep the feedback paths short. The LFCSP package has an exposed pad that should be soldered to the ground plane for thermal and electrical grounding. Route the differential outputs as a pair to minimize common-mode noise. Follow the layout guidelines in the datasheet.
The gain select pin (G1) must be tied to the correct logic level to set the gain. Do not leave it floating. The VOCM pin should be driven by a low-impedance source to set the output common-mode voltage accurately. If the source has a DC offset, use AC coupling at the inputs to avoid saturating the amplifier.
