FN6421.0

Low Noise, Low Power, I2C® Bus, 256 Taps

The ISL22313 integrates a single digitally controlled

potentiometer (DCP), control logic and non-volatile memory

on a monolithic CMOS integrated circuit.

The digitally controlled potentiometer is implemented with a

combination of resistor elements and CMOS switches. The

position of the wipers are controlled by the user through the

I2C bus interface. The potentiometer has an associated

volatile Wiper Register (WR) and a non-volatile Initial Value

Register (IVR) that can be directly written to and read by the

user. The contents of the WR control the position of the

wiper. At power up the device recalls the contents of the

DCP’s IVR to the WR.

The ISL22313 also has 14 general purpose non-volatile

registers that can be used as storage of lookup table for

multiple wiper position or any other valuable information.

The ISL22313 features a dual supply, that is beneficial for

applications requiring a bipolar range for DCP terminals

between V- and VCC.

The DCP can be used as a three-terminal potentiometer or

as a two-terminal variable resistor in a wide variety of

applications including control, parameter adjustments, and

signal processing.

NOTES:

1. Intersil Pb-free plus anneal products employ special Pb-free material sets; molding compounds/die attach materials and 100% matte tin plate

termination finish, which are RoHS compliant and compatible with both SnPb and Pb-free soldering operations. Intersil Pb-free products are

MSL classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.

2. Add “-TK” suffix for 1,000 Tape and Reel option
