Микросхемы и комплектующие AD5143BCPZ100-RL7

Энергонезависимый цифровой потенциометр , 100 кОм, Четверной, I2C, Логарифмический, ± 8%, 2.3 В

The AD5143BCPZ100-RL7 is a quad-channel nonvolatile Digital Potentiometer Solution for 256-position adjustment applications, offering guaranteed low resistor tolerance errors of ±8% and up to ±6mA current density in the Ax, Bx and Wx pins. The low resistor tolerance and low nominal temperature coefficient simplify open-loop applications as well as applications requiring tolerance matching. The linear gain setting mode allows independent programming of the resistance between the digital potentiometer terminals, through the RAW and RWB string resistors, allowing very accurate resistor matching. The high bandwidth and low THD ensure optimal performance for AC signals, making the devices suitable for filter design. The low wiper resistance of only 40R at the ends of the resistor array allows for pin to pin connection. The wiper values can be set through an I²C-compatible digital interface that also reads back the wiper register and EEPROM contents.
