programming rates up to 10MHz. The AS1500 is available in  
four different resistor values. The AS1500 incorporates a  
10k, the AS1501 a 20k, the AS1502 a 50kand the  
AS1503 a 100kfixed resistor. The wiper contact taps the  
fixed resistor at points determined by the 8-bit digital code  
word. The resistance between the wiper and the endpoint of  
the resistor is linear. The switching action is performed in a  
way that no glitches occur. Furthermore the AS150x product  
family includes a shutdown mode, where it consumes less  
than 1µA. The AS150x is available in an 8-pin SOIC  
package. All parts are guaranteed to operate over the  
extended industrial temperature range of –40°C to +125°C.
