MCP4152-502E/SN

Digital Potentiometers Overview

The MCP4152-502E/SN is a single-channel digital rheostat manufactured by Microchip Technology. It features an 8-bit resistor network providing 256 steps and 257 positions, with a nominal resistance (RAB) of 5 kΩ ±20%. The device utilizes volatile RAM for wiper storage and operates via a high-speed SPI serial interface supporting up to 10 MHz at VDD ≥ 2.7V. It functions within a supply voltage range of 1.8V to 5.5V and supports extended industrial temperatures from -40°C to +125°C. Key electrical characteristics include a typical wiper resistance of 75Ω and a bandwidth of 2 MHz.

Digital Potentiometers Feature Summary

• Single-channel digital rheostat configuration with 8-bit resolution (256 steps).
• SPI serial interface compatible with modes 0,0 and 1,1; supports 10 MHz clock rates.
• High-voltage tolerant digital inputs allowing operation up to 12.5V on control pins.
• Brown-out reset protection with a typical threshold of 1.5V.

Digital Potentiometers Applications

• Variable gain control in audio signal processing circuits.
• Programmable biasing networks for analog sensors.
• Adjustable reference voltage generation in measurement systems.

Digital Potentiometers Procurement Notes

Verify the specific suffix 'SN' corresponds to the 8-lead SOIC package as documented in the datasheet. Confirm that the '502' designation strictly indicates a 5 kΩ resistance value. Ensure the 'E' suffix aligns with the required environmental compliance standards for the target application.

Digital Potentiometers Selection Notes

Select this component when a single-channel variable resistance is required without non-volatile memory retention. The 5 kΩ value suits moderate current applications, while the 8-bit resolution provides fine adjustment granularity. Consider the volatile nature of the memory if power loss recovery of the wiper position is not needed.

Digital Potentiometers Part Context

This part belongs to the MCP413X/415X family of 7/8-bit single/dual SPI digital potentiometers with volatile memory. The MCP4152 specifically denotes the dual-rheostat variant within the broader product line, distinguished by its 8-bit resolution and single-channel architecture compared to the 7-bit MCP4132 or dual-potentiometer MCP4251.

Digital Potentiometers Replacement Considerations

Direct functional substitutes within the same volatile memory family include the MCP4151 (potentiometer configuration) and MCP4252 (dual rheostat). For non-volatile requirements, the MCP4162 series offers similar specifications with EEPROM storage instead of RAM.
