ISL23428Dual, 128-Tap, Low Voltage Digitally Controlled Potentiometer (XDCP™) | Data Acquisition | 3 | Active | The ISL23428 is a volatile, low voltage, low noise, low power, 128-tap, dual digitally controlled potentiometer (DCP) with an SPI Bus™ interface. It integrates two DCP cores, wiper switches and control logic on a monolithic CMOS integrated circuit. Each 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 SPI bus interface. Each potentiometer has an associated volatile Wiper Register (WRi, i = 0, 1) that can be directly written to and read by the user. The contents of the WRi controls the position of the wiper. When powered on, the wiper of each DCP will always commence at mid-scale (64 tap position). The low voltage, low power consumption, and small package of the ISL23428 make it an ideal choice for use in battery operated equipment. In addition, the ISL23428 has a VLOGICpin allowing down to 1. 2V bus operation, independent from the VCCvalue. This allows for low logic levels to be connected directly to the ISL23428 without passing through a voltage level shifter. 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. |
ISL23445Quad, 256 Tap, Low Voltage Digitally Controlled Potentiometer (XDCP™) | Data Acquisition | 2 | Obsolete | The ISL23445 is a volatile, low voltage, low noise, low power, 256 tap, quad digitally controlled potentiometer (DCP) with an SPI Bus™ interface. It integrates four DCP cores, wiper switches and control logic on a monolithic CMOS integrated circuit. Each 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 SPI bus interface. Each potentiometer has an associated volatile Wiper Register (WRi, i = 0, 1, 2, 3) that can be directly written to and read by the user. The contents of the WRi controls the position of the wiper. When powered on, the wiper of each DCP will always commence at mid-scale (128 tap position). The low voltage, low power consumption, and small package of the ISL23445 make it an ideal choice for use in battery operated equipment.

ISL23511Low Noise, Low Power, 32 Taps, Push Button Controlled Potentiometer | Integrated Circuits (ICs) | 1 | Active | The Intersil ISL23511 is a three-terminal digitally-controlled potentiometer (XDCP) implemented by a resistor array composed of 31 resistive elements and a wiper switching network. The ISL23511 features a push button control, a shutdown mode, as well as an industry-leading µTQFN package. The push button control has individual PU and PD inputs for adjusting the wiper. To eliminate redundancy the wiper position will automatically increment or decrement if one of these inputs is held longer than one second. Forcing both PU and PD low for more than two seconds activates shutdown mode. Shutdown mode disconnects the top of the resistor chain and moves the wiper to the lowest position, minimizing power consumption. The three terminals accessing the resistor chain naturally configure the ISL23511 as a voltage divider. A rheostat is easily formed by floating an end terminal or connecting it to the wiper. |
