Features

• Four potentiometers per package

• 256 resistor taps

• 10k 50kor 100k total resistance

• SPI serial interface

- No additional level translator for low bus supply

- Daisy Chaining of multiple DCPs

• Maximum supply current without serial bus activity

(standby)

- 5μA @ VCC and VLOGIC = 5V

- 2uA @ VCC and VLOGIC = 1.7V

• Shutdown Mode

- Forces the DCP into an end-to-end open circuit and RWi is

connected to RLi internally

- Reduces power consumption by disconnecting the DCP

resistor from the circuit

• Power supply

- VCC = 1.7V to 5.5V analog power supply

- VLOGIC = 1.2V to 5.5V SPI bus/logic power supply

• Wiper resistance: 70 typical @ VCC = 3.3V

• Power-on preset to mid-scale (128 tap position)

• Extended industrial temperature range: -40°C to +125°C

• 20 Ld TSSOP or 20 Ld QFN packages

• Pb-free (RoHS compliant)

ISL23445WFRZ属于集成电路（IC） > 数字电位计。瑞萨科技有限公司制造生产的ISL23445WFRZ数字电位计数字电位器是一系列集成电路器件，可提供类似于传统机械电位器或变阻器的可调节电阻，但通过电子信号而非机械输入来进行控制。虽然这些器件的电阻可耗散的电能相对有限，但其电子控制能力有助于小型化、自动化和远程控制信号级模拟电路，而这些电路本来可能会使用机械电位器。
