Typical Application Circuit Using ADA4897-1ARJZ-RL as Filters, I/V Converters, Current Summers and ADC Drivers After the I/Q Outputs of the AD9279

Typical Application Circuit Using ADA4897-1ARJZ-RL as Filters, I/V Converters, Current Summers and ADC Drivers After the I/Q Outputs of the AD9279. The ADA4897-1 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 ADA4897-1 make them excellent choices for processing weak Doppler signals. The rail-to-rail output and the high output current drive of the ADA4897-1 make them suitable candidates for the I/V converter, current summer and ADC driver
