high-speed, current output devices. They incorpo-

rate state-of-the-art performance in a miniature

package, achieving maximum output settling times

of 25ns for the 8 and 10-bit models and 50ns

for the 12-bit model. They can be used to drive a

resistor load directly for up to ±1V output or a fast

operational ampiﬁ er (such as DATEL’s AM-500)

for higher voltage outputs with sub-microsecond

settling times. A tapped feedback resistor and a

bipolar offset resistor are included internally to

give ﬁ ve programmable output voltage ranges with

an external operational ampliﬁ er.

construction techniques with advanced circuit

design to realize high-speed current switching.

The design incorporates fast PNP current switches

driving a low-impedance R-2R thin-ﬁ lm ladder

network. The nichrome thin-ﬁ lm resistor network

is deposited by electron beam evaporation on a

lowcapacitance substrate to assure high-speed

performance. The resistors are then functionally

trimmed by laser for optimum linearity.

The DAC-HF design combines proven hybrid
