Texas Instruments LM334M
- Part Number:
- LM334M
- Manufacturer:
- Texas Instruments
- Ventron No:
- 3251504-LM334M
- Description:
- IC CURRENT SOURCE 3% 8SOIC
- ECAD Model:
-
- Datasheet:
- LM334M
Description
The LM134/LM234/LM334 are 3-terminal adjustable current sources with a wide operating current range (1μA to 10mA), excellent current regulation (0.02% /V), and a wide dynamic voltage range (1V to 40V). They operate as true floating current sources with no separate power supply connections. Reverse applied voltages up to 20V draw only a few dozen microamperes of current, allowing the devices to act as both a rectifier and current source in AC applications.
Features
Operates from 1V to 40V
0.02% /V current regulation
Programmable from 1μA to 10mA
True 2-terminal operation
Available as fully specified temperature sensor
±3% initial accuracy
Applications
Bias networks
Surge protection
Low power reference
Ramp generation
LED driver
