LM134H3 Product Details

The LM134/LM234/LM334 are 3-terminal adjustable current sources featuring 10,000:1 range in operating current, excellent current regulation and a wide dynamic voltage range of 1V to 40V. Current is established with one external resistor and no other parts are required. Initial current accuracy is ±3%. The LM134/LM234/LM334 are true floating current sources with no separate power supply connections. In addition, reverse applied voltages of up to 20V will draw only a few dozen microamperes of current, allowing the devices to act as both a rectifier and current source in AC applications.

The sense voltage used to establish operating current in the LM134H3 is 64mV at 25°C and is directly proportional to absolute temperature (°K). The simplest one external resistor connection, then, generates a current with ≈+0.33%/°C temperature dependence. Zero drift operation can be obtained by adding one extra resistor and a diode.

Applications for the current sources include bias networks, surge protection, low power reference, ramp generation, LED driver, and temperature sensing. The LM234-3 and LM234-6 are specified as true temperature sensors with ensured initial accuracy of ±3°C and ±6°C, respectively. These devices are ideal in remote sense applications because series resistance in long wire runs does not affect accuracy. In addition, only 2 wires are required.

The LM134H3 is specified over a temperature range of 55°C to +125°C, the LM234 from 25°C to +100°C and the LM334 from 0°C to +70°C. These devices are available in TO hermetic, TO-92 and SOIC-8 plastic packages.

FAQ:

Q: How does Jotrin guarantee that LM134H3 is the original manufacturer or agent of TI?
We have a professional business development department to strictly test and verify the qualifications of TI original manufacturers and agents. All TI suppliers must pass the qualification review before they can publish their LM134H3 devices; we pay more attention to the channels and quality of LM134H3 products than any other customer. We strictly implement supplier audits, so you can purchase with confidence.
Q: How to find the detailed information of LM134H3 chips? Including TI original factory information, Semiconductors ; Power management ; Voltage references application, LM134H3 pictures?
You can use Jotrin's intelligent search engine, or filter by Semiconductors ; Power management ; Voltage references category, or find it through TI brand manufacturer page.
