Features and Benefits
- 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
- Ultra-Low Full-Channel Receiver Noise Figure of 2.8dB at RIN = RS = 200Ω (Without T/R Switch)
- High Dynamic Range Receiver with 76dBFS SNR at fIN = 5MHz and 2MHz Bandwidth
- Ultra-Low Power Receiver (131mW Per Channel)
The MAX2082 is the industry’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 converter (ADC), and digital highpass filter (HPF) achieves an ultra-low noise figure with RS = RIN = 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 distortion performance at fRF = 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 available 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 specified over a 0°C to +70°C temperature range.
