Product Descriptions

The LM75A or B high-speed 12C interface high-precision temperature sensor development board module has the same random shipping function.

LM75A or B is a high-speed 12C interface temperature sensor that can directly convert temperature into digital signals within the temperature range of -55 ℃ to+125 ℃, and achieve an accuracy of 0.125 ℃. MCU can directly read data from its internal registers through the 12C bus and operate on four data registers through 12C to set different working modes. LM75A has 3 optional logical address pins, allowing 8 devices to be connected simultaneously on the same bus without address conflicts.

Product Characteristic

• 12C bus interface, 7-bit slave address 1001xxx for device address, allowing for the expansion of 8 devices on the same bus; Power supply range: 2.8V~5.5V, temperature range:- 55℃~+125℃;

• The 11 bit ADC provides a temperature resolution of 0.125 ℃;

• Temperature accuracy:

• ±2℃℃(-25'℃℃~100°℃)

• ±3℃(-55°C~125℃C)

• Programmable temperature threshold and hysteresis set point;

• In order to reduce power consumption, the current consumed in turn off mode is only 1.0 μ A;

• When powered on, the device can be used as an independent temperature controller;

  
  

• ESD protection:

  
  

• Under the JESD22A114 standard, it can operate in 2000V HBM mode;

  
  

• Under the JESD22A115 standard, it can operate in 200V MM mode;

  
  

• Under the JESD22-C101 standard, the 1000VCDM mode can be used to:

  
  

• The door lock test conducted under JEDEC standard (JESD78) can reach 100mA;

  
  

• Small 8-pin package: S08, TSSOP8, and ultra small package XSON8U.
