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.
