HIGH SPEED DAC BUFFER
The wide bandwidth and fast settling time of the AD847 makes
it a very good output buffer for high speed current-output D/A
converters like the AD668. As shown in Figure 27, the op amp
establishes a summing node at ground for the DAC output. The
output voltage is determined by the amplifier’s feedback resistor
(10.24 V for a 1 k
resistor). Note that since the DAC gener-
ates a positive current to ground, the voltage at the amplifier
output will be negative. A 100
series resistor between the
noninverting amplifier input and ground minimizes the offset
effects of op amp input bias currents.
