General Description

The EL2005 is a high-speed, FET input buffer similar to ELH0033 and EL2004 but with input specifications significantly improved over the previous types. The input stage employs a cascode configuration to maintain constant input characteristics over the full g10V input range. The input looks like a 3 pF capacitor to ground in almost all cases since the DC bias current is constant with input voltage. In sample and hold circuits this results in an order of magnitude improvement in hold characteristics. Input offset voltage and offset voltage drift are also improved a factor of two over previous types.
