Digital Temperature Sensor IC LM75A SOIC8 +Free Adapter
Digital Temperature Sensor IC LM75A SOIC8 +Free Adapter
Thanks a lot for coming to look.
The kit also comes with 2pcs 8-pin SOIC to DIP PCB adapters.
The LM75A is a temperature-to-digital converter using an on-chip band-gap temperature sensor and Sigma-delta A-to-D conversion technique. The device is
also a thermal detector providing an over-temp detection output. The LM75A contains a number of data registers: Configuration register (Conf) to store the
device settings such as device operation mode, OS operation mode, OS polarity and OS fault queue as described in the functional description section;
temperature register (Temp) to store the digital temp reading, and set-point registers (Tos & Thyst) to store programmable overtemp shutdown and
hysteresis limits, that can be communicated by a controller via the 2-wire serial I2C-bus interface. The device also includes an open-drain output (OS) which
becomes active when the temperature exceeds the programmed limits. There are three selectable logic address pins so that eight devices can be
connected on the same bus without address conflict.
I2C-bus interface with up to 8 devices on the same bus
Power supply range from 2.8 V to 5.5 V
Temperatures range from –55 oC to +125oC
11-bit ADC that offers a temperature resolution of 0.125 oC
Programmable temperature threshold and hysteresis set points
Supply current of 3.5 mA in shut-down mode for power conservation
Stand-alone operation as thermostat at power-up.
ESD protection exceeds 2000 V HBM per JESD22-A114,
200 V MM per JESD22-A115 and 1000 V CDM per JESD22-C101
Latch-up testing is done to JESDEC Standard JESD78 which exceeds 100 mA
