CAT5138SDI-10GT3

Digital Potentiometers Overview

The CAT5138SDI-10GT3 is a digital potentiometer manufactured by onsemi, featuring a 10 kΩ resistance value and 128 programmable positions. It utilizes a linear taper characteristic and operates via a Serial-I2C interface. The component is housed in a 6-pin SC-70 package (also identified as TSSOP6) with plastic/epoxy body material. It supports an operating temperature range from -40 °C to +85 °C and complies with RoHS standards as lead-free. The device is classified under JESD-30 code R-PDSO-G6 and carries an EAR99 ECCN code.

Digital Potentiometers Feature Summary

• 10 kΩ resistance with 128-position linear adjustment
• Serial-I2C digital control interface
• 6-pin SC-70 surface-mount package

Digital Potentiometers Applications

Digital Potentiometers Procurement Notes

Verify the specific datasheet for the CAT5138SDI-10GT3 to confirm electrical parameters and pinout configurations before integration. Ensure compatibility with the target I2C bus voltage levels and check for any specific handling requirements related to the SC-70 package dimensions.

Digital Potentiometers Selection Notes

Select this component when a compact digital potentiometer with I2C control is required. The 128-position resolution offers finer granularity compared to standard 32-tap devices. Verify that the 10 kΩ resistance value aligns with the circuit's impedance requirements and that the SC-70 footprint fits the PCB layout constraints.

Digital Potentiometers Part Context

This part belongs to the CAT5138 series of digital potentiometers from onsemi. It shares the SC-70-6 package form factor with other MiniPot devices but distinguishes itself through the higher 128-position count and I2C interface, contrasting with similar parts like the CAT5110 which typically offer 32 taps.

Digital Potentiometers Replacement Considerations

Direct substitutes may include other onsemi CAT5138 variants with different resistance values or packaging options. Cross-reference pinouts and interface protocols carefully when considering alternatives from other manufacturers.
