VCCOF2,

VCCOF1

Positive VCC Supplies for the Front End of the Output Buffer Circuitry. VCCOF2 is for the output of the IC, while VCCOF1

is for the interstage buffer between the first and second rank track-and-hold amplifiers. Nominal voltage = 2 V

(VCCOF1 + VCCOF2), current = 47 mA (nominal). See Figure 11 for the interface schematic.

VCCTH2,

VCCTH1

Positive Power Supplies for the Track-and-Hold Amplifier Portions of the HMC1061LC5. VCCTH2 is the supply

for second rank track-and-hold core circuitry and VCCTH1 is the supply for the first rank track-and-hold core

circuitry. Nominal voltage = 2 V (VCCTH1 + VCCTH2), current = 140 mA (nominal). See Figure 12 for the interface

schematic.

EPAD

Exposed Pad. The exposed pad must be connected to VEE.
