X9116 Functional Diagram
描述
Support is limited to customers who have already adopted these products.
The Intersil X9116 is a digitally controlled nonvolatile potentiometer designed to be used in trimmer applications. The pot consists of 15 equal resistor segments that connect to the wiper pin through programmable CMOS switches. The tap position is programmed through a 3-wire up/down serial port. The last position of the wiper is stored in a nonvolatile memory location which is recalled at the time of power up of the device. The wiper moves through sequential tap positions with inputs on the serial port. A falling edge on INC (bar) causes the tap position to increment one position up or down based on whether the U/D (bar) pin is held high or low. The X9116 can be used in many applications requiring a variable resistance. In many cases it can replace a mechanical trimmer and offers many advantages such as temperature and time stability as well as the reliability of a solid state solution.

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.

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.

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.
