X93154 Functional Diagram
描述
Support is limited to customers who have already adopted these products.
The Intersil X93154 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 3-wire interface. The potentiometer is implemented by a resistor array composed of 31 resistive elements and a wiper switching network. 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 during a subsequent power-up operation. The device is connected as a two-terminal variable resistor and can be used in a wide variety of applications including: $$ Bias and Gain Control $$ LCD Contrast Adjustment

- 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 750 KB an139 2005年6月30日AI 生成的摘要: The document details the design of power supplies using Intersil’s XDCP mixed signal products. It explains four key circuit schematics: Front End, Power Mesh, Secondary Control, and Primary Control, highlighting their interconnections. The Front End converts AC line power to an unregulated 320V DC, incorporating protection and EMI filtering components. The Power Mesh is a single switch forward DC/DC converter that regulates 320V DC to 12V DC at 10A, using a cascode transistor arrangement and a digitally controlled switching frequency to meet EMI requirements.
- 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.
- 应用说明英语PDF 467 KB an1149 2005年5月03日AI 生成的摘要: The document details circuits using Intersil digitally controlled potentiometers (X9C103, X9312) combined with op amps (LT1226, OP37, LT1028) for applications like null adjustment, amplifier biasing, and proportional-integral temperature control. It explains modes controlled by NADJ/ADJ signals, automatic nulling via feedback loops, and bias stabilization in high-output buffer amplifiers. The circuits optimize gain, bandwidth, noise, and minimize distortion and power consumption. It also covers clocking options for nulling and temperature control using digital potentiometers and comparators.
- 应用说明英语PDF 280 KB an1157 2005年4月29日AI 生成的摘要: Digitally controlled potentiometers (XDCPs) enable precise power supply and DC to DC converter control by allowing cascading configurations for fine and coarse voltage adjustments. 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.
- 应用说明英语PDF 324 KB an124 2005年4月27日AI 生成的摘要: Digitally-controlled potentiometers have key analog parameters including number of taps (16 to 256), end-to-end resistance (1kΩ to 1MΩ), wiper resistance (~40Ω), wiper current (1-3mA), power rating (10-50mW), resolution, noise, linearity, and temperature coefficients. Voltage limits range from ±5V to ±15V on pins. Absolute linearity ensures accuracy within one least significant bit, while relative linearity guarantees tap-to-tap accuracy within 0.2 LSB. Temperature coefficients affect resistance stability. Various circuit techniques exist to mitigate these limitations. The document also includes usage notices, quality grades, and liability disclaimers from Renesas Electronics.
