Product Details

describe:

The TMP116 family (TMP116, TMP116N) consists of a low-power, high-accuracy A3972SB temperature sensor with integrated EEPROM memory. The TMP116 provides 16-bit temperature results with 0.0078°C resolution and ±0.2°C accuracy without calibration. The TMP116 is compatible with I 2 C and SMBus interfaces, has programmable alarm functions, and supports up to four devices on a single bus.

The TMP116 consumes minimal current, which, in addition to providing energy savings, minimizes self-heating and improves measurement accuracy. The TMP116 operates from 1.9 V to 5.5 V and typically consumes 3.5 μA.

Over the device operating temperature range of –55°C to +125°C, the TMP116 exceeds the accuracy of a Class A RTD while consuming less than one-fifth the excitation current typical of a PT100 RTD. The TMP116 is easier to use than RTDs and requires no calibration, external circuitry, matching traces and Kelvin connections.

The TMP116 unit is 100% tested on NIST traceable production settings and verified using equipment calibrated to ISO/IEC 17025 accredited standards.
