This document discusses operational amplifier applications, including as voltage to current and current to voltage converters. It describes voltage to current converters with floating loads and grounded loads, using inverting amplifiers. Applications of voltage to current converters include diode match finders, zener diode testers, relay drivers, and LED drivers. Current to voltage converters are also discussed. Their applications include sensing current through photocells, in light intensity meters, and in digital to analog converters. The document was authored by Mr. C.R. Shinde of the Electrical Engineering Department at Matoshri College of Engineering & Research Centre in Nashik, India.
