Each channel provides 256 discrete resistance steps from 0 to 50kΩ, controlled via an I²C interface. The linear taper means resistance changes linearly with wiper position — suited for precision voltage divider, programmable current source, or sensor trim applications where a logarithmic curve is not required. Non-volatile memory stores the wiper position and configuration across power cycles, so the device powers up at the last programmed setting without needing a microcontroller to re-initialize it on each boot. ## Package, supply, and temperature range Housed in a 16-ball CSBGA (4x4 mm) package — the 0.80 mm ball pitch demands a controlled reflow profile and X-ray inspection to verify solder joint integrity. The supplier device package is 16-CSBGA (4x4), a fine-pitch BGA with a 4 mm square footprint. Operating temperature spans -40°C to 95°C, suitable for industrial and telecom environments. The integrated temperature sensor provides on-die temperature monitoring accessible via the I²C bus — useful for thermal compensation of the wiper resistance or system-level temperature logging. ## Active production — sourcing and compliance ROHS3 compliant — fully lead-free with no RoHS exemptions. The part carries a ±20% resistance tolerance and a ±50 ppm/°C temperature coefficient, typical for digital potentiometers in this class.","metaTitle":"Analog Devices DS1856B-M50+ Digital Potentiometer, 50kΩ","metaDescription":"DS1856B-M50+ digital potentiometer from Analog Devices. 50kΩ resistance, 256 taps, I²C interface, linear taper, dual channel, non-volatile memory.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Taper":"Linear","Package":"Tray","Features":"Temperature Sensor","Interface":"I²C","Tolerance":"±20%","Memory Type":"Non-Volatile","Configuration":"Rheostat","Mounting Type":"Surface Mount","Number of Taps":"256","Package / Case":"16-LBGA, CSPBGA","lifecycle_stage":"eol_hot","Voltage - Supply":"2.85V ~ 5.5V","Resistance (Ohms)":"50k","Number of Circuits":"2","Operating Temperature":"-40°C ~ 95°C","Supplier Device Package":"16-CSBGA (4x4)","Temperature Coefficient (Typ)":"±50ppm/°C"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.49","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$5.49000","currency":"USD"},{"qty":10,"price":"$4.92700","currency":"USD"},{"qty":25,"price":"$4.65760","currency":"USD"},{"qty":80,"price":"$4.03650","currency":"USD"},{"qty":230,"price":"$3.82948","currency":"USD"},{"qty":810,"price":"$3.43620","currency":"USD"},{"qty":1620,"price":"$3.10500","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/54d8a00961553747ce76ecbec2153dee.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the taper and resistance range of the DS1856B-M50+?","answer":"The DS1856B-M50+ has a linear taper, 50 kΩ end-to-end resistance, 256 taps per channel, and two independent channels.
