The CAT5128TBI-00GT3 is a digital potentiometer from onsemi, designed to offer precise control and adjustment in various electronic applications. This device features a 100kΩ resistance with a tolerance of ±20%, making it suitable for applications requiring high precision. The CAT5128TBI-00GT3 is housed in a compact SOT23-8 package, ideal for surface-mount applications where space is a constraint. It operates within a supply voltage range of 2.5V to 5.5V, ensuring compatibility with a wide range of power supplies. The device also includes 32 taps, providing granular control over resistance settings. The wiper resistance is typically 150Ω, ensuring minimal impact on circuit performance. The CAT5128TBI-00GT3 is configured with a linear taper, allowing for uniform resistance changes across the adjustment range. It features an Up/Down interface (UP, DN) for intuitive control and adjustment. The memory type is volatile, meaning it retains settings only while power is applied. This digital potentiometer is REACH unaffected and has a moisture sensitivity level (MSL) of 1, indicating it is suitable for unlimited exposure in standard environmental conditions.
