Digital Potentiometers datasheet and documents for CAT5140ZI50GT-MP
Digital Potentiometers Overview
The CAT5140ZI-50-GT3 is a single-channel digital potentiometer IC from onsemi, featuring 256 taps and non-volatile memory. It operates within a supply voltage range of 2.5 V to 5.5 V with a typical current consumption of 1 mA. The device offers a resistance value of 50 kOhms with a linear taper and a temperature coefficient of 100 PPM/°C. Communication is handled via an I2C interface, and it is housed in an MSOP-8 package suitable for surface mount applications across a temperature range of -40°C to +85°C.
Digital Potentiometers Feature Summary
- Non-volatile storage retains wiper position after power loss
- I2C serial interface for simplified control
- Single potentiometer with 256 discrete tap positions
- Linear resistance taper with 50 kOhm nominal value
Digital Potentiometers Applications
- Audio volume control systems
- Sensor calibration circuits
- Variable gain amplifier settings
- Power supply voltage adjustment
Digital Potentiometers Procurement Notes
Verify the exact suffix against official documentation, as 'GT-MP' may indicate specific packaging or manufacturing plant codes not explicitly detailed in standard public datasheets. Confirm availability status as some variants are marked end-of-life. Ensure RoHS compliance details match the specific revision required for your assembly process.
Digital Potentiometers Selection Notes
Select this component when non-volatile retention is critical for maintaining setpoints without battery backup. The I2C interface requires only two pins, saving board space compared to 3-wire alternatives. Verify that the 50 kOhm resistance and 256-tap resolution meet the precision requirements of the target application circuit.
Digital Potentiometers Part Context
This part belongs to the CAT5140 series of digitally programmable potentiometers. It shares the core architecture with other CAT51xx devices but distinguishes itself through the combination of high tap count (256) and I2C connectivity, differentiating it from lower-resolution or SPI-based counterparts in the same family.
Digital Potentiometers Replacement Considerations
Direct pin-compatible replacements within the same series include CAT5140ZI-50-T3. For similar functionality with different interfaces, consider CAT5113ZI-50-T3 (3-wire serial) or CAT5110SDI-00GT3 (2-wire serial), noting differences in tap count and memory type.
