LM75A Temperature Sensor I2C High Precision 11 Bit ADC Temp Resolution 0.125℃





Features:

LM75A is a high-speed I2C interface, temperature sensor,

in the temperature range -55 ℃ ~ + 125 ℃ The temperature was directly converted to digital signals,

and to achieve the accuracy of 0.125 ℃.

MCU can be read directly via I2C bus data in its internal registers,

and through I2C to four data registers operates to set different operating modes.

LM75A has three selectable logic address pins,

making it possible to connect eight devices without address conflict on the same bus.

I2C bus interface, the device address 7 slave address 1001xxx,

can expand outside eight devices on the same bus;

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

11 ADC provides a temperature resolution of 0.125 ℃;

Temperature accuracy:

± 2 ℃ (-25 ℃ ~ 100 ℃)

± 3 ℃ (-55 ℃ ~ 125 ℃)

Programmable temperature threshold and hysteresis set points;

In order to reduce power consumption, the current consumption in shutdown mode is only 1.0μ A;

On power-up the device can be used as a stand-alone temperature controllers;

ESD protection:

In JESD22A114 standard, it can be 2000V HBM mode;

In JESD22A115 standard, can 200V MM mode;

In JESD22-C101 standard, it can be 1000V CDM model;

In JEDEC Standard (JESD78) latch-up testing done up to 100mA;
Small 8-pin package: SO8, TSSOP8 and ultra-small package XSON8U.
