 Digital Potentiometer (POT), Dual 64-Tap, with 2-wire Interface

制造商:ON

中文数据手册

产品信息

The CAT5419 is two digital POTs integrated with control logic and 16 bytes of NVRAM memory.
A separate 6-bit control register (WCR) independently controls the wiper tap position for each digital POT. Associated with each wiper control register are four 6-bit nonvolatile memory data registers (DR) used for storing up to four wiper settings. Writing to the wiper control register or any of the non-volatile data registers is via a 2-wire serial bus (I²C-like). On power-up, the contents of the first data register (DR0) for each of the two potentiometers is automatically loaded into its respective wiper control registers (WCR).
The Write Protection (
) pin protects against inadvertent programming of the data register.
The CAT5419 can be used as a potentiometer or as a two terminal, variable resistor. It is intended for circuit level or system level adjustments in a wide variety of applications.
  • Two linear-taper digital potentiometers
  • 64 resistor taps per potentiometer
  • End-to-end resistance 2.5 kΩ, 10 kΩ, 50 kΩ or 100 kΩ
  • Potentiometer control and memory access via 2-wire interface (I²C like)
  • Low wiper resistance, typically 80 Ω
  • Four non-volatile wiper settings for each potentiometer
  • Recall of wiper settings at power up
  • 2.5 to 6.0 volt operation
  • Standby current less than 1 µA
  • 1,000,000 nonvolatile WRITE cycles
  • 100 year nonvolatile memory data retention
  • Write protection for data register
