LTS115
Voltage to Current_4-20mA
Description
LTS115/116/117 is a two-wire V/I converter mainly used to match V/I circuits implemented in operational amplifier schemes, packaged in SOIC-8
The MSOP-8 package, as well as the small volume version, has significant cost and area advantages over operational amplifier solutions. The output current is determined by IIN,
Formula: IOUT=100 × IIN. Meet the low-cost and high-performance requirements of some users for 4-20mA.
Advantages And Characteristics
Two wire V/I conversion chip
Vref output voltage: LTS115 is 2.5V, LTS116 is 4.096V, LTS117-1 is 2.5V, LTS117-2 is 4.096V
