Analog Devices AD7376
The AD7376 provides a single channel, 128-position digitallycontrolled variable resistor (VR) device. This device performs the same electronic adjustment function as a potentiometer or variable resistor. These products were optimized for instrument and test equipment applications where a combination of high voltage with a choice between bandwidth or power dissipation are available as a result of the wide selection of end-to-end terminal resistance values.| Part No. | AD7376 |

SDO ؎15 V Operation Digital Potentiometer AD7376* FUNCTIONAL BLOCK DIAGRAM AD7376 Q 7-BIT SERIAL REGISTER SDI CLK CS D CK 7 7-BIT LATCH R 7 VDD A W B SHDN VSS GND RS SHDN The AD7376 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.
