LM75AIMMX/NOPB

LM75AIMMX/NOPB is TI’s LM75A digital temperature sensor with an I2C interface, offered in Pb-free 8‑pin packages (NOPB). It provides ambient temperature measurement over a wide range and reports data via a temperature register.
Key points:
- Measurement range: roughly -55°C to +125°C.
- Resolution: typically 9-bit (about 0.5°C per LSB); data is read from a temperature register (plus optional configuration and alert registers).
- Interface: I2C-compatible, with optional ALERT/INT output for threshold events.
- Power: operates from about 2.8–5.5 V; designed for low power and easy shutdown modes.
- Package: 8-pin, RoHS Pb-free (IMMX). Available in common small packages (MSOP-8/SOIC-8 variants).
Common use: ambient temperature sensing in consumer electronics, computers, HVAC, and other systems needing simple, low-cost temperature monitoring.
Quick start: connect Vcc and GND, pull up SDA/SCL to Vcc, read the temperature register to obtain the current temperature. For exact register map, address pins, and timing details, consult the LM75A datasheet.

Concise features of LM75AIMMX/NOPB:
- I2C/SMBus-compatible digital temperature sensor
- -55°C to +125°C measurement range
- Temperature data: 9-bit default (0.5°C); extended 11-bit mode (0.125°C) via config
- 16-bit temperature register, two’s complement data
- 2-wire serial interface (up to Fast-mode 400 kHz)
- THYS and TOS programmable temperature thresholds
- OS/Alert output with selectable mode (Comparator or Interrupt) and polarity
- Open-drain alert output
- Address pins (A0–A2) for up to 8 devices on the bus
- Supply voltage: 2.8 V to 5.5 V
- 8-pin MSOP package (LM75AIMMX), RoHS-compliant (NOPB)

The LM75AIMMX/NOPB is supplied in an 8-pin VSSOP (MM) package (VSSOP-8), Pb‑free (NOPB).

- Pin count: 8 pins (8-pin package).
- Function: Digital I2C temperature sensor. Uses three address pins (A0–A2) to set the I2C address and provides an ALERT/THERM output; power via VCC and GND; data/clock via SDA and SCL.
