CAT5114YI-50-G

Digital Potentiometers Overview

The CAT5114YI-50-G is a single digital potentiometer IC manufactured by onsemi, featuring 32 adjustable taps with a linear taper characteristic. The device incorporates non-volatile memory to retain the wiper setting during power-down conditions. It operates within a supply voltage range of 2.5 V to 6.0 V and draws a typical standby current of 100 µA. The component utilizes a serial three-wire interface for control and is housed in an 8-pin TSSOP surface-mount package.

Digital Potentiometers Feature Summary

• Non-volatile EEPROM storage retains wiper position after power loss
• Serial 3-wire interface (CS, U/D, INC) for up/down control
• Single supply operation from 2.5 V to 6.0 V
• Ultra-low standby current of 10 nA

Digital Potentiometers Applications

• Automated gain control in instrumentation systems
• Volume or tone adjustment in audio equipment
• Remote calibration of sensor bias voltages
• System configuration via microcontroller interfaces

Digital Potentiometers Procurement Notes

Verify the specific suffix 'YI' against official datasheets to confirm the TSSOP-8 package type and industrial temperature rating. Confirm RoHS compliance status through manufacturer documentation prior to integration. Check for end-of-life notices as this series may have limited availability compared to newer replacements.

Digital Potentiometers Selection Notes

Select this part when a single-channel digital potentiometer with 32 positions is required. Ensure the application supports the 3-wire serial protocol rather than I2C or SPI. Verify that the 50 kΩ resistance value fits the circuit impedance requirements and that the 2.5 V to 6.0 V supply range matches the system voltage.

Digital Potentiometers Part Context

This component belongs to the CAT511x family of linear-taper digital potentiometers. It serves as an electronic replacement for mechanical pots in applications requiring automated adjustment. The CAT5114 variant specifically provides 32 taps, distinguishing it from the 100-tap CAT5113 and the 11-tap CAT5112 models.

Digital Potentiometers Replacement Considerations

Direct pin-compatible alternatives include the CAT5114LI-50-G (PDIP package) and CAT5114GVI-50TE13 (SOIC package). Verify package dimensions and lead pitch differences before substituting into existing PCB layouts.
