AD817

H IGH SP EED D AC BUFFER

(10.24 V for a 1 kΩ resistor). Note that since the DAC gener-

ates a positive current to ground, the voltage at the amplifier

output will be negative. A 100 Ω series resistor between the

noninverting amplifier input and ground minimizes the offset

effects of op amp input bias currents.

T he wide bandwidth and fast settling time of the AD817 make

it a very good output buffer for high speed current output D/A

converters like the AD668. As shown in Figure 38, the op amp

establishes a summing node at ground for the DAC output. T he

output voltage is determined by the amplifier’s feedback resistor
