CAT5132
16 Volt Digital
Potentiometer (POT)
with 128 Taps
and I²C Interface
Description
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
the I²C 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.
The CAT5132 has two voltage supplies: V_CC, the digital supply and
V+, the analog supply. V+ can be much higher than V_CC, allowing for
16 V analog operations.
The CAT5132 can be used as a potentiometer or as a two-terminal
variable resistor.
