High-Gain Vector Multipliers
MAX2047 ELECTRICAL CHARACTERISTICS
(Typical Operating Circuit as shown in Figure 1; V
rent range = 0 to 4mA (if using a current-mode DAC), and differential input voltage range = 0 to 0.707V (if using a voltage-mode
DAC). If using a current-mode DAC, voltage mode I/Q inputs are left open. If using a voltage-mode DAC, all current-mode I/Q inputs
are left open. Typical values are at V
