Overview of DS18B20Z

The DS18B20Z is a programmable resolution 1-Wire digital thermometer optimized for high accuracy temperature measurement and low power consumption. It provides excellent performance for various applications, including analog and digital signal switching.

Pinout

The DS18B20Z pinout refers to the configuration and function of each pin in its SOIC-8 package. This package typically includes a diagram showing the layout of the pins when viewed from the top down with pins named sequentially. Each pin on the DS18B20Z has a specific role such as power supply input, ground connection, or signal interface. The pinout details are crucial for integrating this component into a circuit as they ensure correct connections for optimal device performance. Designers and engineers must refer to the datasheet provided by the manufacturer to get accurate information regarding each pin's function and electrical characteristics.

Features

  • Unique 1-Wire Interface: The DS18B20Z requires only one port pin for communication, reducing component count and simplifying distributed temperature-sensing applications with multidrop capability.
  • Programmable Resolution: The device measures temperatures from -55°C to +125°C (-67°F to +257°F) with ±0.5°C accuracy from -10°C to +85°C, and offers programmable resolution from 9 bits to 12 bits.
  • No External Components Required: The DS18B20Z does not require any external components for operation, making it a convenient choice for many applications.
  • Parasitic Power Mode: The device operates in parasitic power mode, requiring only 2 pins (DQ and GND) for operation, which simplifies distributed temperature-sensing applications with multidrop capability.
  • Flexible User-Definable Nonvolatile (NV) Alarm Settings: The DS18B20Z allows users to define nonvolatile alarm settings with an alarm search command that identifies devices with temperatures outside programmed limits.
  • Unique 64-Bit Serial Code: Each device has a unique 64-bit serial code stored in on-board ROM, making it easy to identify and address individual devices.
