The X9268TS24ZT1 is a dual digitally-controlled potentiometer featuring 256 resistor taps with a resolution of 0.4%. It operates via a 2-wire serial interface, allowing for write, read, and transfer operations. Each potentiometer includes 16 nonvolatile data registers for storing multiple wiper positions, which can be recalled upon power-up. The device has a typical wiper resistance of 100Oc at V+ = 5V and V- = -5V, and it supports a power supply range of ±2.7V to ±5.5V. Available in 50kOc and 100kOc versions, it is designed for low power consumption with a maximum standby current of less than 5µA. The product is housed in a 24-lead SOIC package and is RoHS compliant. It is suitable for various applications, including audio control, signal processing, and parameter adjustments in electronic circuits.
The X9268 integrates 2 digitally controlled potentiometer (XDCP) on a monolithic CMOS integrated circuit.brbr The digital controlled potentiometer is implemented using 255 resistive elements in a series array. Between each element are tap points connected to the wiper terminal through switches. The position of the wiper on the array is controlled by the user through the 2-Wire bus interface. Each potentiometer has associated with it a volatile Wiper Counter Register (WCR) and a four nonvolatile Data Registers that can be directly written to and read by the user. The contents of the WCR controls the position of the wiper on the resistor array though the switches. Powerup recalls the contents of the default Data Register (DR0) to the WCR.brbr The XDCP 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.
