Ultrasound VGA Integrated
with CW Octal Mixer
Typical Operating Characteristics (continued)
(Figure 7, V_CC = V_REF = 4.75V to 5.25V, V_GND = 0, LOW_PWR = 0, M4_EN = 0, CW_FILTER = 1, TMODE = 0, PD = 0, CW_VG = 0,
CW_M1 = 0, CW_M2 = 0, CW mixer outputs pulled up to 11V through four separate ±0.1% 115Ω resistors, differential mixer inputs
are driven from a low-impedance source.
