Ultrasound AFE Transceiver Chip for CMUT Transducers

Overview

The MVUS01 ultrasound transducer interface is the first generation of high-voltage (HV) ultrasound ASICs intended for portable medical imaging probes and other markets. The chip supports pulsing ultrasonic transducers, with excitation voltages of up to 50V, and has high gain and low noise receivers, for
increased sensitivity to ultrasonic echoes. The chip is programmable to support a wide range of loads, at reasonable current consumption levels.

Key Features

  • 8-channel ultrasound transceiver analog front-end
  • RX front-end with analog output (T/R switch, TIA)
  • High Voltage TX Driver that supports voltages up to 50V with input pulse shaping. Supports a wide range of transducer capacitances (200pF-520pF)
  • Each RX channel is designed to drive 300?-6k? resistive loads and up to 200pF
  • capacitive loads
  • Programmable input TIA gain: 78, 68, 63, 58 dB?
  • Wide RX input bandwidth up to 5MHz
  • Operating temperature range from 0 to 85°C
  • Fully compliant SPI interface, with a fast command for T/R switch configuration

Applications

  • Ultrasound Medical Imaging
  • Ultrasound Proximity Sensing
  • Non-destructive Testing
