PRODUCT OVERVIEW  
INPUT/OUTPUT CONNECTIONS  
The DAC-HF Series of hybrid DAC’s are ultra  
high-speed, current output devices. They incorpo-  
rate state-of-the-art performance in a miniature  
The DAC-HF design combines proven hybrid  
construction techniques with advanced circuit  
design to realize high-speed current switching.

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 1ꢀ output or a fast  
operational ampifier (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 five programmable output voltage ranges with  
an external operational amplifier.  
driving a low-impedance R-2R thin-film ladder  
network. The nichrome thin-film 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.
