INA143: INA143 as a voltage controlled current source

Hello,

A simple configuration that can implement the INA143 as a voltage controlled current source is an “Improved” Howland Current Pump circuit. The link below explains this circuit more in-depth. Please refer to page 5 in the article. Integrated difference amplifiers like the INA143 can be a great selection for an “Improved” Howland Current Pump; however this is dependent on the type of loads your circuit is connected to and other design constraints.

Hi,

datasheet of INA105 has some nice example circuits showing voltage controlled current sources :-)
