X9313 Functional Diagram
Description
The Intersil X9313 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. 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:
- Control
- Parameter adjustments
- Signal processing

- Application NotePDF 820 KB an1481 Oct 03, 2008AI-generated Summary: This section explains using a Digital Control Potentiometer (DCP) for video gain control and cable compensation to maintain low noise and high image quality in video applications. It discusses the challenges of gain control, including parasitic capacitance and wiper resistance in the DCP, which affect bandwidth and gain stability at high frequencies. Solutions include adding resistors and capacitors to compensate for these parasitic effects, ensuring stable gain across the video frequency range. Simulation and test results confirm the effectiveness of these compensation techniques.
- Application NotePDF 281 KB an1425 May 22, 2008AI-generated Summary: 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.
- Application NotePDF 750 KB an139 Jun 30, 2005AI-generated Summary: 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.
- Application NotePDF 534 KB an133 Jun 06, 2005AI-generated Summary: 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.
- Application NotePDF 467 KB an1149 May 03, 2005AI-generated Summary: 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.
