ISL22323規(guī)格書(shū)詳情

The ISL22323 integrates two digitally controlled

potentiometers (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 (WRi) and a non-volatile Initial Value

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

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

corresponding wiper. At power up the device recalls the

contents of the DCP’s IVRi to the correspondent WRi.

The ISL22323 also has 13 general purpose non-volatile

registers that can be used as storage of lookup table for

multiple wiper position or any other valuable information.

The ISL22323 features a dual supply, that is beneficial for

applications requiring a bipolar range for DCP terminals

between V- and VCC.

Each DCP can be used as three-terminal potentiometers or

as two-terminal variable resistors in a wide variety of

applications including control, parameter adjustments, and

signal processing.
