超声可变增益放大器

MAX2037是8通道可变增益放大器(VGA)，专门针对超声成像和多普勒仪应用而设计，具有高线性、高动态范围以及低噪声的性能。每个放大器都具有差分输入和输出，总增益范围为42dB (典型值)。此外，VGA还具有超低的输出基准噪声，适合与12位ADC连接。\n MAX2037的VGA经过优化后，具有小于±0.25dB的绝对增益误差，确保通道间超声波束形成的聚集误差最小。器件的差分输出可通过外部无源抗混叠滤波器直接驱动超声波ADC。每个放大器的输出具有可切换的箝位功能，用于限制输出信号，从而防止ADC过驱动或饱和。\n 器件的动态性能经过优化后，大大降低了失真，支持二次谐波成像。在VOUT = 1 \n• 8通道架构 \n• 高集成度适合超声成像应用 \n• 与超声VGA及CW多普勒波束形成器MAX2038引脚兼容 \n• 最大增益、增益范围以及输出基准噪声性能经设计优化，适合与12位ADC连接 \n• 最大增益为29.5dB \n• 总增益范围为42dB \n• 在5MHz下，具有22nV/的超低输出基准噪声 \n• 与10位版本的MAX2035/MAX2036引脚兼容 \n• 绝对增益误差为±0.25dB \n• 可切换的输出VGA箝位功能，不会造成ADC过驱动 \n• 全差分VGA输出，可直接驱动ADC \n• 增益可调，动态范围达42dB \n• VOUT = 1.5VP-P，f;
