　　Introduction

　　The DS3930 contains six 256-position nonvolatile （NV） potentiometers （see Figure 1）， which makes the DS3930 an ideal device for applications needing multiple voltage references. All six potentiometers share a common low side. The potentiometers are separated into two groups of three 50kΩ potentiometers in parallel. Each group of three shares a common high side. The potentiometer wiper voltage can vary between 0V and VHI in 256 steps， where VHI is the voltage on HI0-2 or HI3-5.
