CAT5132  
16 Volt Digital  
Potentiometer (POT)  
with 128 Taps  
and I2C Interface  
Description  
http://onsemi.com  
The CAT5132 is a high voltage digital POT with non-volatile wiper  
setting memory, operating like a mechanical potentiometer. The tap  
points between the 127 equal resistive elements are connected to the  
wiper output via CMOS switches. The switches are controlled by a  
7-bit Wiper Control Register (WCR). The wiper setting can be stored  
in a 7-bit non-volatile Data Register (DR). The WCR is accessed via  
MSOP10  
Z SUFFIX  
CASE 846AE

the I C serial bus.  
Upon power-up, the WCR is set to mid-scale (1000000). After the  
power supply is stable, the contents of the DR are transferred to the  
WCR and the wiper is returned to the memorized setting.  
MARKING DIAGRAM  
The CAT5132 has two voltage supplies: V , the digital supply and  
CC  
ANBx  
YMR  
V+, the analog supply. V+ can be much higher than V , allowing for  
CC  
16 V analog operations.  
The CAT5132 can be used as a potentiometer or as a two-terminal  
variable resistor.  
ANBU = CAT5132ZI-10-GT3  
ANBK = CAT5132ZI-50-GT3  
ANBP = CAT5132ZI-00-GT3  
Y = Production Year (Last Digit)  
M = Production Month (1-9, A, B, C)  
R = Production Revision
