6 / 8 page 6 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.

The maximum error at zero (half scale) will not exceed the Linearity Error.
