ISL22512WFB8Z

Digital Potentiometers Overview

The ISL22512WFB8Z is a single-channel, non-volatile digital potentiometer manufactured by Intersil (Renesas). It features a 10kΩ total resistance with 16 discrete tap positions. The device utilizes a button interface for manual control of the wiper position and includes an automatic decrement/increment function. It operates on a single power supply ranging from 2.7V to 5.5V. The component is housed in an 8-lead SOIC package designed for surface mount installation.

Digital Potentiometers Feature Summary

• Non-volatile memory retains wiper position data without power
• Button-controlled interface with auto-increment/decrement capability
• Low standby current of 3µA in shutdown mode
• Operates within a 2.7V to 5.5V single supply range

Digital Potentiometers Applications

• Volume control in audio equipment
• Gain adjustment in signal processing circuits
• Voltage reference trimming
• User interface settings adjustment

Digital Potentiometers Procurement Notes

Verify the manufacturer designation as Intersil or Renesas Electronics Corporation depending on the production era. Confirm the suffix WFB8Z corresponds to the 8-lead SOIC package and lead-free (Pb-Free) RoHS compliance status. Ensure the operating temperature range meets the specific application requirements of -40°C to +125°C.

Digital Potentiometers Selection Notes

Select this component when a single-channel, non-volatile digital potentiometer with manual button control is required. The 10kΩ resistance value and 16-tap resolution are suitable for precision adjustments. Consider the 8-pin SOIC footprint for PCB layout compatibility. Verify that the button interface fits the system design compared to serial interface alternatives.

Digital Potentiometers Part Context

This part belongs to the ISL2251x family of low-power, non-volatile digital potentiometers. The family offers various resistance values and interface options. The ISL22512 specifically provides 16 taps and button control, distinguishing it from serial interface variants like the ISL22511 or higher-resolution models.

Digital Potentiometers Replacement Considerations

Check for direct equivalents within the ISL2251x series such as the ISL22511 or ISL22513 if interface or resolution differences are acceptable. Verify pinout compatibility and electrical specifications before substitution.
