LM75A or B high-speed I2C interface high-precision temperature sensor development board module shipped with the same function
LM75A or B is a high-speed I2C interface temperature sensor that can directly convert temperature into a digital signal within the temperature range of -55°C to +125°C, and can achieve an accuracy of 0.125°C. The MCU can directly read the data in its internal registers through the I2C bus, and can operate the 4 data registers through I2C to set different working modes. LM75A has 3 optional logical address pins, allowing 8 devices to be connected to the same bus at the same time without address conflicts.
characteristic:
I2C bus interface, device address 7-bit slave address 1001xxx, 8 devices can be expanded on the same bus;
Power supply range: 2.8V～5.5V, temperature range: -55℃～+125℃;
11-bit ADC provides temperature resolution up to 0.125℃;
Temperature accuracy:
±2℃(-25℃~100℃)
±3℃(-55℃~125℃)
Programmable temperature thresholds and hysteresis set points;
In order to reduce power consumption, the current consumed in shutdown mode is only 1.0μA;
The device can be used as an independent temperature controller when powered up;
ESD protection:
Under the JESD22A114 standard, the 2000V HBM mode can be passed;
Under the JESD22A115 standard, 200V MM mode can be passed;
Under the JESD22-C101 standard, 1000V CDM mode can be passed;
Latch-up test under JEDEC standard (JESD78) can reach 100mA;
Small 8-pin packages: SO8, TSSOP8 and ultra-small package XSON8U.
