LT3092 APPLICATIONS INFORMATION Introduction The LT3092 is a versatile IC that operates as a 2-terminal programmable current source with the addition of only two external resistors; no external bypass capacitors are needed for stability. The LT3092 is easy to use ...
Page 9
... In addition, the current source’s value will dif- fer between applications and its connection may be GND referenced, power supply referenced or fl oating in a signal line path. Linear Technology strongly recommends that stability be tested in situ for any LT3092 application. In LT3092 applications with long wires or PCB traces, the inductive reactance may cause instability ...
