Overview
The MCP4017T-103E/LTVAO is a single-channel digital potentiometer manufactured by Microchip Technology. It features a 7-bit resolution providing 128 discrete resistance steps and utilizes an I²C serial interface for control. The device supports a wide operating voltage range from 1.8V to 5.5V, with analog characteristics specified between 2.7V and 5.5V. It offers a typical wiper resistance of 100Ω and operates within an extended temperature range of -40°C to +125°C. The component includes volatile memory and a power-on default wiper setting at mid-scale.
Feature Summary
- 7-bit resolution with 128 taps for precise resistance adjustment
- I²C serial interface supporting standard and fast mode protocols
- Wide supply voltage operation from 1.8V to 5.5V
- Extended industrial temperature range (-40°C to +125°C)
Applications
- Programmable gain amplifiers
- Voltage reference trimming
- Audio volume control
Procurement Notes
Verify the specific 'VAO' suffix against official Microchip documentation to confirm if it denotes automotive qualification or a specific packaging variant. Ensure compatibility with the SC70-6 package dimensions and pinout configuration before finalizing procurement specifications.
Selection Notes
Select this model for applications requiring low pin count and simple I²C control. The 10kΩ nominal resistance (indicated by '103') suits moderate impedance circuits. Consider the volatile memory nature; external storage is required if resistance settings must persist after power loss.
Part Context
This part belongs to the MCP4017/18/19 family of digital potentiometers. While the MCP4018 offers potentiometer configuration, the MCP4017 is specifically designed for rheostat configurations. The 'LT' indicates the SC70-6 package, and the '103' suffix specifies the 10kΩ resistance value.
Replacement Considerations
The MCP40D17T-103E/LTY is a parameter-equivalent alternative within the same product family. Verify that the replacement maintains the required rheostat configuration and I²C address compatibility.
