MAX2082
Low-Power, High-Performance Octal Ultrasound
Transceiver with Integrated AFE, Pulser,
T/R Switch, and CWD Beamformer
Benefits and Features
● Minimizes PCB Area and Design Cost
• 8 Full Channels of HV Pulser, T/R-Switch, LNA
Input and Feedback Coupling Caps, LNA, VGA,
AAF, CWD Mixers, 12-Bit ADC, and Digital HPF in
a Small 10mm x 23mm CSBGA Package
● Integrated HV Pulser for Simpler System Design
• High-Voltage 3 Level Pulsers (Up to ±105V) with
Active Return to Zero and Internal Power-Supply
Drivers for Reduced External Components
• Programmable Pulser Current Capability from 0.5A
to 2A for Reduced Power Consumption in Lower
Voltage Transmit Modes Like CWD
• Extremely Low Propagation Delay Pulsers (18ns)
with Excellent Rise and Fall Matching for Excellent
THD2 Performance (-43dBc at 5MHz)
● Integrated High-Performance Receiver Improves
System Sensitivity
• Ultra-Low Full-Channel Receiver Noise Figure
of 2.8dB at R
IN
= R
S
= 200Ω (Without T/R Switch)
• High Dynamic Range Receiver with 76dBFS SNR
at f
IN
= 5MHz and 2MHz Bandwidth
• Ultra-Low Power Receiver (131mW Per Channel)
General Description
The MAX2082 is the world’s first fully-integrated octal
ultrasound transceiver. The device is optimized for high-
channel-count, high-performance portable and cart-based
ultrasound systems. The easy-to-use transceiver allows
the user to achieve high-end 2D and Doppler imaging
capability using substantially less space and power.
The transceiver transmitters are high-performance, 3-level
2A pulsers capable of generating high-voltage pulses up
to ±105V.
The highly compact receiver with T/R switch, LNA, input
coupling and feedback capacitors, variable gain amplifier
(VGA), anti-aliasing filter (AAF), analog-to-digital con-
verter (ADC), and digital highpass filter (HPF) achieves
an ultra-low noise figure with R
S
= R
IN
= 200Ω at a very
low 131mW per-channel power dissipation at 50Msps.
The receive channel has been optimized for second
harmonic imaging with -66dBFS second harmonic distor-
tion performance at f
RF
= 5MHz over the full gain range.
The full receive channel exhibits an exceptional 76dBFS
SNR at 5MHz with a 2MHz bandwidth.
Separate mixers for each channel are made avail-
able for optimal CWD sensitivity yielding an impressive
149dBc/Hz dynamic range per channel at 1kHz offset
from the 1.25MHz carrier.
The MAX2082 octal ultrasound front-end is available in
a small 10mm x 23mm CSBGA package and is specified
over a 0°C to +70°C temperature range.
