    產(chǎn)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
