General Description

The ELH0002 is a general purpose hybrid current amplifier buffer that is built on a single substrate.

The ELH0002 is ideal for current buffering operational amplifiers without changing the characteristics of the Op Amp. The ELH0002 uses a completely symmetrical circuit to provide a low output impedance when both sourcing and sinking current. This means the output will drive coaxial cables and other capacitive loads with equivalent rise and fall times.

Features
