集成了八路CW混频器的超声VGA

8通道可变增益放大器(VGA)和可编程8路混频器阵列MAX2038是针对高线性度、高动态范围以及低噪声性能的超声成像和多普勒应用而设计的。每一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还具有极低的输出参考噪声，适合与12位ADC连接。\n MAX2038 VGA经设计优化，绝对增益误差小于±0.25dB，以确保超声波束形成时的通道间聚集误差最小。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用ADC。每个放大器的输出还提供可使能或禁止的箝位功能，以限制输出信号，从而防止ADC过驱动或饱和。\n 器件的动态性能经过了优化，从而大大降低了失真，支持二次谐波 \n• 8通道架构 \n• 高集成度适合超声成像应用 \n• 与超声VGA MAX2037引脚兼容 \n• VGA特性 \n• 最大增益、增益范围以及输出参考噪声性能均经过优化，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• 5MHz时，具有22nV/的超低输出参考噪声 \n• 绝对增益误差为±0.25dB \n• 每通道功耗为120mW \n• 可使能或禁止的输出VGA箝位功能，消除ADC过驱动 \n• 全差分VGA输出，可直接驱动ADC \n• 可变增益范围可实现42dB动态范围 \n• VOUT = 1.5VP-P，fIN = 5MHz时，H;
