Each of the two independent pots is 45kΩ end-to-end, with a typical wiper resistance of 160Ω. The wiper position is stored in non-volatile memory, so the setting persists through power cycles. Communication is over an I²C interface, and the part includes a mute function, selectable I²C address, and zero-cross sensing to eliminate clicks during wiper transitions. Housed in a 16-pin SOIC package (3.90 mm width), the DS1882Z-050+ operates over the industrial temperature range of -40°C to +85°C, making it suitable for audio mixing consoles, broadcast equipment, automotive infotainment, and industrial control panels where ambient temperatures can climb. ## Logarithmic taper — why it matters for audio A linear pot changes resistance by the same step per tap; a logarithmic pot approximates the human ear's response, where equal increments in perceived loudness require exponential resistance changes. The DS1882Z-050+'s logarithmic taper means a 64-step volume control feels natural across the full range, from whisper to full output. If your design calls for a linear curve — for example, as a voltage divider in a servo feedback loop — this part is the wrong choice; look for a linear-taper digital pot instead. ## I²C interface and address flexibility The DS1882Z-050+ communicates via the I²C bus, a two-wire serial interface common in mixed-signal systems. The selectable address feature lets you place up to two of these devices on the same bus without address conflicts — useful for stereo or multi-channel audio boards where each channel needs its own pot. The mute function allows instant attenuation to minimum volume without reprogramming the wiper register, handy for power-on muting or fault conditions. ## Zero-cross sense and pop-free transitions The zero-cross sense feature synchronises wiper changes to the AC zero-crossing point of the audio signal, which prevents audible clicks or pops when the volume is adjusted. This is a differentiator versus simpler digital pots that change resistance immediately on receipt of an I²C command, potentially generating a transient that couples into the audio path. ## Lifecycle and sourcing The DS1882Z-050+ is listed as Active and ROHS3 compliant. For BOM planning, this means no last-time-buy pressure and normal lead times through distribution.","metaTitle":"DS1882Z-050+ Digital Potentiometer, 45kΩ Logarithmic, 64-Tap","metaDescription":"Maxim DS1882Z-050+ dual 45kΩ logarithmic digital pot with 64 taps, I²C interface, non-volatile memory, mute & zero-cross sense. -40°C to +85°C, 16-SOIC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["DC-DC Power Modules"],"specifications":{"Taper":"Logarithmic","Package":"Tube","Features":"Mute, Selectable Address, Zero-Cross Sense","Interface":"I²C","Tolerance":"±20%","Memory Type":"Non-Volatile","Configuration":"Potentiometer","Mounting Type":"Surface Mount","Number of Taps":"64","Package / Case":"16-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"4.5V ~ 7V","Resistance (Ohms)":"45k","Number of Circuits":"2","Operating Temperature":"-40°C ~ 85°C","Supplier Device Package":"16-SOIC","Temperature Coefficient (Typ)":"750ppm/°C","Resistance - Wiper (Ohms) (Typ)":"160"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.87","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$4.87000","currency":"USD"},{"qty":10,"price":"$4.37500","currency":"USD"},{"qty":25,"price":"$4.13600","currency":"USD"},{"qty":100,"price":"$3.58450","currency":"USD"},{"qty":250,"price":"$3.40068","currency":"USD"},{"qty":500,"price":"$3.05142","currency":"USD"},{"qty":1000,"price":"$2.57348","currency":"USD"},{"qty":2500,"price":"$2.44481","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/61b288b7cab86f5ba59834f9d99e664d.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What does the logarithmic taper mean for my audio design?","answer":"The logarithmic taper means the resistance changes in a pseudo-log curve per tap, matching human loudness perception.
