APPLICATION NOTE 5765

Maximize the Performance of High-Signal-to-Noise Ratio (SNR) Ultrasound Receivers with an Optimized System Design

By: John Scampini

Abstract: The current generation of ultrasound receivers and transceivers, like the MAX2082 have been optimized for superior SNR performance. Advancements in low-power, high-resolution analog-to-digital converters (ADCs) and low-output-noise variable-gain amplifiers (VGAs) have made these advancements possible. To take advantage of this improved receiver performance, however, it is necessary for the designers to understand how the gain settings in these devices, as well as the dynamic range, filtering, detection, and display mapping of the received data, must be properly optimized. The purpose of this application note is to review these topics in sufficient detail so the reader can better optimize their systems and take advantage of these improved devices.
