TITMP1075DSGR
Overview
The TMP1075DSGR is a high-accuracy digital temperature sensor designed to provide a direct replacement for industry-standard LM75 and TMP75 sensors. It features a 12-bit ADC that offers 0.25 degree C accuracy over a wide operating range while consuming very low power. The device is housed in a compact 2mm x 2mm WSON package and supports both I2C and SMBus interfaces with an integrated alert function.
Why Choose This Part
The TMP1075DSGR offers a significant upgrade in accuracy and power efficiency, drawing only 2.7uA typical quiescent current and 0.37uA in shutdown mode. Its 1.7V to 5.5V supply range ensures compatibility with modern low-voltage microcontrollers. Furthermore, it is pin-to-pin and software compatible with existing xx75 designs, allowing for easy performance upgrades without board layout changes.
Applications
Key Specifications
Getting Started
To evaluate the sensor, the TMP1075EVM is the recommended hardware platform for rapid prototyping. Communication is handled via standard I2C or SMBus; ensure the ADDR pins are strapped correctly to set the desired peripheral address. In firmware, developers can use the One-shot mode to minimize power consumption by triggering conversions only when needed.
