Description
The STLM75 is a high-precision digital CMOS temperature sensor IC with a sigma-delta
temperature-to-digital converter and an I
for general applications such as personal computers, system thermal management,
electronics equipment, and industrial controllers, and is packaged in the industry standard
8-lead TSSOP and SO8 packages.
The device contains a band gap temperature sensor and 9-bit ADC which monitor and
digitize the temperature to a resolution up to 0.5 °C. The STLM75 is typically accurate to
(±3 °C - max) over the full temperature measurement range of –55 °C to 125 °C with ±2 °C
accuracy in the –25 °C to +100 °C range. The STLM75 is pin-for-pin and software
compatible with the LM75B.
The STLM75 is specified for operating at supply voltages from 2.7 V to 5.5 V. Operating at
3.3 V, the supply current is typically (125 µA).
The on-board sigma-delta analog-to-digital converter (ADC) converts the measured
temperature to a digital value that is calibrated in degrees centigrade; for Fahrenheit
applications a lookup table or conversion routine is required.
The STLM75 is factory-calibrated and requires no external components to measure
temperature.
Serial communications
The STLM75 has a simple 2-wire I
user to access the data in the temperature register at any time. It communicates via the
serial interface with a master controller which operates at speeds up to 400 kHz. Three pins
(A0, A1, and A2) are available for address selection, and enable the user to connect up to 8
devices on the same bus without address conflict.
In addition, the serial interface gives the user easy access to all STLM75 registers to
customize operation of the device.
