Choosing and using N-Channel Dual J-FETs

Monolithic dual FET's have made parameter matching obsolete—eliminating laborious sorting and grading. Their improved performance (e.g. 5µV/°C offset drift) and reduced cost make them a natural choice for many applications. But there are important differences in construction among dual J-FETs, which determine temperature coefficients, performance, reliability, and consequently, choice for a given application.
