Ultrasound Variable-Gain Amplifier
Typical Operating Characteristics (continued)
(Figure 2, VCC = VREF = 4.75V to 5.25V, VGND = 0, 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 val-
ues are at VCC = VREF = 5V, VCM = 3.0V, TA = +25°C, unless otherwise noted.)
