ISL95710 Functional Diagram
描述
Support is limited to customers who have already adopted these products.
The Intersil ISL95710 is a digitally controlled potentiometer (XDCP). The device consists of a resistor array, wiper switches, a control section, and nonvolatile memory. The wiper position is controlled by a Up/Down interface. The potentiometer is implemented by a resistor array composed of 127 resistive elements and a wiper switching network. Between each element and at either end are tap points accessible to the wiper terminal. The position of the wiper element is controlled by the CS, U/D, and INC inputs. The position of the wiper can be stored in nonvolatile memory and then be recalled upon a subsequent power-up operation. The device can be used as a three-terminal potentiometer or as a two-terminal variable resistor in a wide variety of applications including:
- Industrial and automotive control
- Parameter and bias adjustments
- Amplifier bias and control

- 应用说明英语PDF 281 KB an1425 2008年5月22日AI 生成的摘要: Digitally Controlled Potentiometers (DCPs) offer precise resistance control with configurations in both serial and parallel modes, featuring fixed resistors and various resistance options. The ISL22317 model provides 1% precision with 128 taps and can function as a two-terminal variable resistor or three-terminal potentiometer, delivering high accuracy and low temperature coefficient. DCPs can outperform DACs in fine tuning within limited ranges, offering better resolution with fewer bits. Resolution varies with voltage and tap count, as detailed in the provided tables. Usage guidelines and liability disclaimers emphasize proper application and safety considerations.
- 应用说明英语PDF 534 KB an133 2005年6月06日AI 生成的摘要: The document explains how digitally controlled potentiometers (XDCPs) enable programmability in amplifier circuits by adjusting cutoff frequency and gain. It details the design of a non-inverting amplifier with variable resistors forming an RC low pass filter and gain control. Techniques to reduce potentiometer resistance for high-frequency applications are described, allowing gain from 1 to 2 and cutoff frequency from 130kHz to over 1MHz. The amplifier’s parameters are controlled via a serial bus, enabling computer-based customization.

These devices store wiper settings in nonvolatile memory, ensuring long-term reliability and simplifying manufacturing and testing. XDCPs improve repeatability, reduce human error, and enhance resistance to environmental stress, making them superior to mechanical potentiometers in power applications.

It emphasizes user responsibility for product design, disclaims liability for damages, and prohibits unauthorized modifications or reverse engineering. Products are categorized by quality grades with specific application recommendations. Users must comply with safety, environmental, and export regulations. Renesas disclaims warranties and liability for improper use or noncompliance. Contact information for global sales offices is provided.

It details resistor values for DOSA and Vicor modules, showing how DCPs adjust output voltage within a ±10% range by changing code values. It also covers output voltage setting and margining techniques for POLA and DOSA modules using external resistors and FETs, highlighting that replacing these with DCPs enables software-controlled voltage adjustment with multiple steps.
- 应用说明英语PDF 503 KB an9675 1999年8月13日AI 生成的摘要: Effective Number of Bits (ENOB) depends critically on precise coherence in A/D sampling, with small frequency shifts significantly impacting accuracy. Unwrapping reconstructs coherently sampled sine waves, while windowing controls spectral leakage by shaping the acquisition window. Resampling and interpolation adjust sample sets to avoid leakage in FFT analysis. Different window functions balance side lobe levels and bandwidth, affecting spectral resolution and leakage reduction.
- 应用说明英语PDF 287 KB an9705 1997年2月21日AI 生成的摘要: Coherent sampling requires the ratio of signal frequency to sampling frequency to be a rational number, expressed as ko/N. When this condition is not met, frequency smearing occurs across bins. Data Acquisition Systems (DAS) can mitigate this by windowing, fixing sampling frequency and tuning input frequency, or fixing input frequency and tuning sampling frequency. The latter two methods are practical for most systems. Pseudo-code illustrates the frequency response for non-integer ko values.
