CAT5409
Digital Potentiometer (POT), Quad 64-Tap, with I2C Interface
制造商:ON
产品信息
The CAT5409 is four 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 non-volatile 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 four potentiometers is automatically loaded into its respective wiper control register (WCR).
The Write Protection (
) pin protects against inadvertent programming of the data register.
The CAT5409 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.
