LM75A or B, high-speed I2C interface, high-precision temperature sensor, development board module, shipped randomly, with the same function

The LM75A or B is a high-speed I2C-interface temperature sensor that can directly convert temperature into digital signals within a temperature range of -55℃ to +125℃, achieving an accuracy of 0.125℃. The MCU can directly read data from its internal registers via the I2C bus and operate on four data registers through I2C to set different operating modes. The LM75A has three selectable logic address pins, allowing up to eight devices to be connected on the same bus without address conflicts.

Characteristics:

I2C bus interface, device address 7-bit slave address 1001xxx, can expand up to 8 devices on the same bus;

Power supply range: 2.8V~5.5V, temperature range: -55℃~+125℃;

The 11-bit ADC provides temperature resolution up to 0.125℃;

Temperature accuracy:

±2℃(-25℃~100℃)

±3℃(-55℃~125℃)

Programmable temperature threshold and hysteresis setpoint;

To reduce power consumption, the current consumed in shutdown mode is only 1.0 μA;

When powered on, the device can function as an independent temperature controller;

ESD protection:

Under the JESD22A114 standard, it can pass 2000V HBM mode;

Under the JESD22A115 standard, it can pass through the 200V MM mode;

Under the JESD22-C101 standard, it can pass the 1000V CDM mode;

The latch-up test conducted under the JEDEC standard (JESD78) can reach 100mA;

Small 8-pin packages: SO8, TSSOP8, and ultra-small package XSON8U.
