What are the key features of AD605BRZ-RL?
- Dual independent VGA channels with -14 dB to +34 dB gain range controlled by a single voltage input
- 40 MHz -3 dB bandwidth enabling high-frequency analog signal processing in ultrasound and communications
- Voltage-controlled gain with linear-in-dB response for consistent dB-per-volt sensitivity across gain range
- Low noise figure preserving signal integrity in receiver front-end and medical imaging applications
- 16-pin SOIC package with RoHS e3 compliant lead-free construction for production environments
What is AD605BRZ-RL used for?
The AD605BRZ-RL serves as a dual-channel variable gain stage in medical ultrasound receivers, where time-gain compensation requires precise gain control from -14 dB to +34 dB over each scan depth. Wireless communications receivers use it for automatic gain control loops that maintain constant signal levels into ADCs across varying RF field strengths up to 40 MHz bandwidth. Instrumentation and test equipment front ends benefit from its linear-in-dB control law for calibrated attenuation and amplification without lookup-table linearization.

Frequently Asked Questions
What is the gain control range of AD605BRZ-RL and how is it set in a receiver design?
The AD605BRZ-RL offers a programmable gain range from -14 dB to +34 dB, totaling 48 dB of adjustment, controlled by a DC voltage applied to the gain control input pin. A 0V to 1V control signal spans the full range at approximately 40 dB per volt, enabling a DAC or AGC loop to set gain with millivolt-level precision for each of the 2 independent channels.
How does AD605BRZ-RL's 40 MHz bandwidth suit ultrasound imaging signal chains?
Ultrasound transducers in the 2 MHz to 15 MHz clinical imaging range require a gain stage with bandwidth well above the signal frequency to avoid phase distortion across the scan line. The AD605BRZ-RL's 40 MHz -3 dB bandwidth provides more than 2x headroom above a 15 MHz probe signal, preserving pulse shape fidelity and enabling accurate time-gain compensation from -14 dB to +34 dB as echo depth increases.
For an automatic gain control loop, why is AD605BRZ-RL's linear-in-dB response advantageous?
A linear-in-dB VGA produces constant gain change in dB per unit control voltage regardless of the absolute gain setting, so the AGC loop dynamics remain the same at -14 dB as at +34 dB. This simplifies loop filter design because the plant gain is constant, avoiding the need for a nonlinear compensator or lookup table that would be required with a linear-in-amplitude controlled amplifier.
How many VGA channels does AD605BRZ-RL integrate and how does that affect system BOM in a stereo or I/Q receiver?
AD605BRZ-RL integrates 2 independent VGA channels in the 16-pin SOIC package, directly serving I and Q paths in a quadrature receiver or left and right channels in a stereo audio processing chain without a second IC. This dual integration halves the VGA IC count, reduces the number of decoupling capacitors needed per IC, and cuts PCB area by approximately 50% compared to two single-channel alternatives.
