Ultrasound VGA Integrated
with CW Octal Mixer
Typical Operating Characteristics
(Figure 7, VCC = VREF = 4.75V to 5.25V, VGND = 0V, PD = 0, VG_CLAMP_MODE = 1, fRF = 5MHz, capacitance to GND at each of
the VGA differential outputs is 60pF, differential capacitance across the VGA outputs is 10pF, RL = 1kΩ, TA = 0°C to +70°C. Typical
values are at VCC = VREF = 5V, VCM = 3.0V, TA = +25°C, unless otherwise noted.)
