使用 ADA4896-2ACPZ-RL 作為 AD9279 I/Q 輸出之后的
濾波器、I/V
轉換器、電流
加法器和 ADC
驅動器的典型應用電路。 ADA4896-2 在 AD9279 的 I/Q 解調器之后用于超聲應用中的 CW
多普勒路徑。多普勒信號通常在 100 Hz 到 100 kHz 之間。 ADA4896-2 的低本底噪聲和高動態范圍使其成為處理微弱多普勒信號的絕佳選擇。 ADA4896-2 的軌到軌輸出和高輸出電流驅動使其成為 I/V 轉換器、電流加法器和 ADC 驅動器的合適候選者

Typical Application Circuit Using ADA4896-2ACPZ-RL as Filters, I/V Converters, Current Summers and ADC Drivers After the I/Q Outputs of the AD9279. The ADA4896-2 is used in the CW Doppler path in the ultrasound application after the I/Q demodulators of the AD9279. Doppler signals can be typically between 100 Hz to 100 kHz. The low noise floor and high dynamic range of the ADA4896-2 make them excellent choices for processing weak Doppler signals. The rail-to-rail output and the high output current drive of the ADA4896-2 make them suitable candidates for the I/V converter, current summer and ADC driver
