MAX5479ETE+

MAXIM INTEGRATED PRODUCTS  MAX5479ETE+  非易失性数字电位器, 100 kohm, 双, I2C, 线性, ± 25%, 2.7 V

The is a dual non-volatile linear taper digital potentiometer in 16 pin TQFN package. This device combines two independently controlled 256 position potentiometers and the device control is achieved through I²C interface. The low temperature coefficient makes the device ideal for applications requiring a low temperature coefficient variable resistor such as low drift, programmable gain amplifier circuit configurations.
