Intersil X9252 Low Power Quad 256-tap 2-Wire Bus + Up/Down Interface Data Sheet

Category: Converters, Electronics, Intersil Corporation

Intersil X9252 Overview

The X9252 from Intersil is a low-power, quad digitally-controlled potentiometer (XDCP) featured in the 2-Wire Bus + Up/Down Interface Data Sheet. This integrated circuit consolidates four XDCPs on a single CMOS chip. Each potentiometer is composed of 255 resistive elements, resulting in high-resolution adjustment capabilities through an array connected to wiper terminals via switches.

Key Features

Flexible Control Interfaces: Customers can manipulate the wiper position using either the Up/Down (U/D) interface or the 2-wire bus.
Multiple Registers for Voltage Adjustment: Comes with a volatile Wiper Counter Register (WCR) and four non-volatile Data Registers (DRs) for precise wiper position control.
Memory and Recall Functions: Automatic recall of wiper positions from default data registers upon power-up ensures consistent performance.
High Resolution: Featuring 256 wiper tap points, the device guarantees 0.4% resolution for smooth voltage transitions.
Energy Efficient: Exhibits a standby current under 100pA and a maximum wiper current of 3mA.
Versatile Operating Ranges: Compatible with a Vcc range from 2.7V to 5.5V and offers varying total pot resistance versions.
Longevity and Reliability: Certified to endure 100,000 data changes per bit per register with over 100 years of data retention.

The X9252 is suitable for multiple applications, including setting bias voltages and implementing various network configurations. Its robust design comes in various packaging options compliant with RoHS standards, such as the 24-pin SOIC and TSSOP with Pb-free plus anneal.

Availability and Ordering

Intersil offers the X9252 in several model variations based on resistance value and temperature range capabilities, all between -40°C to 85°C. These include options for both Pb-free and standard finishes, ensuring broad application usage in environmentally conscious markets.
