MEDICAL ULTRASOUND TGC DRIVING THE
AD9050, A 10-BIT, 40 MSPS ADC
The AD604 is an ideal candidate for the time gain control (TGC)
amplifier that is required in medical ultrasound systems to limit
the dynamic range of the signal that is presented to the ADC.
Figure 52 shows a schematic of an AD604 driving an AD9050
in a typical medical ultrasound application.
The gain is controlled by means of a digital byte that is input to
an AD7226 DAC that outputs the analog gain control signal.
The output common-mode voltage of the AD604 is set to VPOS/2
by means of an internal voltage divider. The VOCM pin is
bypassed with a 0.1 μF capacitor to ground.
The DSX output is optionally filtered and then buffered by
an AD9631 op amp, a low distortion, low noise amplifier. The
op amp output is ac-coupled into the self-biasing input of an
AD9050 ADC that is capable of outputting 10 bits at a 40 MSPS
sampling rate.
