AD5204 Datasheet PDF

●The AD5204BRZ10 is a 4-channel Digital Potentiometer performs the same electronic adjustment function as a potentiometer or variable resistor. Each channel of the AD5204 contains a fixed resistor with a wiper contact that taps the fixed resistor value at a point determined by a digital code loaded into the SPI-compatible serial-input register. The resistance between the wiper and either endpoint of the fixed resistor varies linearly with respect to the digital code transferred into the VR latch. The variable resistor offers a completely programmable value of resistance between the A terminal and the wiper or the B terminal and the wiper. Each VR has its own VR latch that holds its programmed resistance value. These VR latches are updated from an internal serial-to-parallel shift register that is loaded from a standard 3-wire serial-input digital interface. Eleven data bits make up the data-word clocked into the serial input register.

● Multiple independently programmable channels

● Potentiometer replacement

● SPI-compatible serial data input

● power-ON midscale preset
