Frequently Asked Questions
What is the TMP102AIDRLT and what does it measure?
The TMP102AIDRLT is a high-accuracy digital temperature sensor from Texas Instruments. It measures ambient temperature with +/-0.5C accuracy (0C to 65C) and +/-1C accuracy over the full -40C to +125C range. It outputs 12-bit digital readings via I2C, making it easy to interface with microcontrollers without any ADC or signal conditioning.
What interface does TMP102AIDRLT use and how many devices can share a bus?
TMP102AIDRLT uses the I2C interface supporting Standard (100kHz), Fast (400kHz), and Fast Mode Plus (3.4MHz) speeds. It supports up to 4 devices on a single I2C bus via the ADD0 address pin, which can be connected to GND, V+, SDA, or SCL to select one of four addresses.
What is the supply voltage range and power consumption of TMP102AIDRLT?
TMP102AIDRLT operates from 1.4V to 3.6V, making it compatible with 1.8V, 2.5V, and 3.3V systems. Active current is only 10uA typical at 3.3V. In shutdown mode, current drops to 1uA, ideal for duty-cycled battery-powered applications using one-shot conversion.
What are common alternatives to TMP102AIDRLT?
Common alternatives include the TMP112AIDRLT (pin-compatible, same accuracy in smaller SOT-563), LM75A (I2C, SO-8), and MCP9808 (Microchip, +/-0.25C, I2C, DFN). For lower cost, the LMT70 (analog output) or STTS751 (ST, I2C) are also widely used in temperature sensing applications.
What package does TMP102AIDRLT come in and what is the pin count?
TMP102AIDRLT is housed in a SOT-563 package with 6 pins. This is an extremely compact 1.6mm x 1.2mm surface-mount package suited for space-constrained designs. The R suffix in the part number indicates tape-and-reel packaging with 3000 units per reel.
