TMP121-EP datasheet

 

Description

The TMP121 and TMP123, TMP121-EP are SPI-compatible temperature sensors available in the tiny SOT23-6 package. Requiring no external components, the TMP121 and TMP123 are capable of measuring temperatures within 2°C of accuracy over a temperature range of –40°C to 125°C. Low supply current and a supply range from 2.7 V to 5.5 V make the TMP121 and TMP123 excellent candidates for low-power applications. The TMP121 and TMP123 are ideal for extended thermal measurement in a variety of communication, computer, consumer, environmental, industrial, and instrumentation applications.

Features

• Controlled Baseline – One Assembly/Test Site, One Fabrication Site
• Extended Temperature Performance of -40°C to 125°C
• Enhanced Diminishing Manufacturing Sources (DMS) Support
• Enhanced Product-Change Notification
• Qualification Pedigree
• Digital Output: SPI-Compatible Interface
• Resolution: 12-Bit + Sign, 0.0625°C

AD590 Datasheet – Current Output Temperature Transducer

Posted on by Pinout

Part Number: AD590

Function: 2-Wire, Current Output Temperature Transducer

Package: TO-52, Metal Can Type

Manufacturer: Intersil

Pinouts:
AD590 datasheet

Description

The AD590 is an integrated-circuit temperature transducer which produces an output current proportional to absolute temperature. The inherent low cost of a monolithic integrated circuit combined with the elimination of support circuitry makes the AD590 an attractive alternative for many temperature measurement situations. Linearization circuitry, precision voltage amplifiers, resistance measuring circuitry and cold junction compensation are not needed in applying the AD590. In the simplest application, a resistor, a power source and any voltmeter can be used to measure temperature.

Features

1. Linear Current Output : 1uA/oK
2. Wide Temperature Range :  -55’C to 150’C
3. Two-Terminal Device Voltage In/Current Out
4. Wide Power Supply Range : +4V to +30V
5. Sensor Isolation From Case
6. Low Cost
