Intersil X9015 – 32-Tap Single Digitally Controlled Potentiometer Datasheet

Category: Converters, Electronics, Intersil Corporation

Overview

The Intersil X9015 datasheet presents a 32-tap, single digitally controlled potentiometer designed for applications that require a digitally controlled variable resistor. This volatile device includes a resistor string with 31 resistors facilitating the wiper output to connect with any nodes between the connecting resistors.

Functionality and Interface

The X9015’s wiper position is altered by signals on the 3-wire up/down port which responds to a falling edge on the increment pin, and the direction of movement is governed by the state of the up/down pin. The initial power-up position is set at Tap #15.

Main Characteristics

The potentiometer operates at Vcc ranging from 2.7V to 5V. Operational current consumption is capped at 50µA maximum, with a standby current of just 1µA maximal, which implies low power consumption. The X9015 is offered with a total resistance of 10kΩ or 50kΩ and is available in 8 Ld SOIC and 8 Ld MSOP packages, both RoHS compliant and Pb-free.

Block Diagram and Pinout

The block diagram contained within the datasheet reveals an intricate design composed of a 5-Bit Up/Down Counter, control circuitry, a resistor array, and device select, increment, and up/down functionality tied to the 3-wire port.

The pinout illustration shows the SOIC/MSOP layout including pins for Vcc (Supply Voltage), CS (Device Select), INC (Increment), U/D (Up/Down), wiper output Rw/Vw, and Vss (Ground).

Ordering Information and Temperature Ranges

Communication regarding part numbers, marking, temperature ranges, and package types is crystal clear. It details different item variants with specified temperature ranges, either from 0 to +70°C or -40 to +85°C. Notably, a ‘T1’ suffix indicates tape and reel packaging.

The Intersil Pb-free plus anneal products mentioned align with RoHS compliance, signifying their adherence to particular environmental standards without compromising performance in both SnPb and Pb-free soldering operations.
