该器件具有高达15.5V的输出电压，是第一款内置温度传感器、ADC以及查找表(LUT)的高度集成非易失数字电位器系列产品，具有与标准数字电位器相近的成本。





DS3501提供了一个ADC可寻址的36字节LUT，查找的温度跨度范围为-40℃至+100℃。可以使用LUT输出加上非易失初值寄存器(IVR)的值或LUT输出直接替代IVR的值，作为7位线性电位器的输入。该架构可支持许多应用，例如LCD背板、光接收器以及工业控制这类理想控制电压随温度变化而变的应用。DS3501专门设计可适合于电压随温度变化线性改变或非线性改变两种不同的应用

-The DS3501 is a 7-bit, nonvolatile (NV) digital potentiometer

featuring an output voltage range of up to 15.5V.

Programming is accomplished by an I2C-compatible

interface, which can operate at speeds of up to 400kHz.

External voltages are applied at the RL and RH inputs to

define the lowest and highest potentiometer outputs.

The DS3501 contains an on-chip temperature sensor

and associated analog-to-digital converter (ADC). The

ADC output addresses a 36-byte NV lookup table

(LUT). The LUT output can drive the pot directly or be

added to an NV initial-value register (IVR) to drive the

pot. This flexible LUT-based architecture allows the

DS3501 to provide a temperature-compensated potentiometer

output with arbitrary slope.
