output. Matched switching times and fast switching will
reduce glitches considerably. (Measured as one half the
Product of duration and amplitude.)
Decoupling and Grounding
For best accuracy and high frequency performance, the
grounding and decoupling scheme shown in Figure 1 should
be used. Decoupling capacitors should be connected close
to the HI-DAC80V (preferably to the device pins) and should
be tantalum or electrolytic bypassed with ceramic types for
best high frequency noise rejection.
Reference Supply
An internal 6.3V reference is provided on board the
HI-DAC80V. The voltage (pin 24) is accurate to 0.8% and
must be connected to the reference input (pin 16) for
specified operation. This reference may be used externally,
provided current drain is limited to 2.5mA. An external buffer
amplifier is recommended if this reference is to be used to
drive other system components. Otherwise, variations in the
load driven by the reference will result in gain variations of
the HI-DAC80V. All gain adjustments should be made under
constant load conditions.
