Manufacturer Documentation
Technical values were checked against Analog Devices (Maxim Integrated) documentation. Use the linked datasheet as the controlling source and re-check revisions before PCB release or firmware qualification.
DS18B20Z selection and design context
DS18B20Z is cataloged as a Digital Temperature Sensor in the DS18B20 family. Its recorded function is programmable-resolution 1-Wire digital thermometer with unique 64-bit serial code. Selection should be based on the complete electrical limits, package drawing and ordering suffix rather than the abbreviated family code.
- Resolution: Programmable 9 to 12 bit. Use the worst-case datasheet limit rather than a typical headline value.
- Accuracy: ±0.5°C from -10°C to +85°C. Use the worst-case datasheet limit rather than a typical headline value.
- Interface: 1-Wire. Confirm logic levels, signaling mode, host support and required external components.
- Supply Voltage: 3.0 V to 5.5 V. Check rail compatibility, tolerance and sequencing under worst-case conditions.
Application and qualification considerations
When evaluating this sensor, confirm measurement range, sensitivity, noise, output data rate, interface voltage, calibration needs and mechanical orientation. For a new design, review power-up behavior, interface timing, absolute maximum ratings, thermal limits and any external-component requirements in the latest manufacturer documentation. Existing-board replacement work should additionally confirm pinout, footprint, firmware assumptions and qualification grade.
Procurement checks for DS18B20Z
The recorded package is 8-pin SOIC, 150 mil, the temperature range is -55°C to +125°C, and the lifecycle status is Production as of 2026-07-20. Before ordering, confirm the exact MPN on the label, packing format, quantity, date-code requirements, traceability documents and current factory status.
