Mechanical Characteristics
The TQ6122 DAC is packaged in a proprietary 44-pin
multilayer ceramic package which provides high-speed,
controlled-impedance interconnects and integral power
supply bypassing. The leads are set on 0.050” centers,
and are formed for gull-wing surface mounting. Figure
8 shows the pinout diagram of the packaged IC as seen
from the top, opposite the cavity side; Figure 9 lists pin
numbers, names and I/O levels. Figure 10 illustrates
the pertinent dimensions of the package and Figure 11
shows the mounting footprint.
Since the TQ6122 dissipates on the order of 1.3 W,
adequate heat sinking is essential for proper operation
of the device. Figure 12 shows one possible heat sink
arrangement based on a multi-finned “Top Hat” heat
sink available from Thermalloy. An environment with a
minimum of 100 fpm (feet per minute) of forced air
cooling is assumed; >200 fpm is preferred.
