Elantec Semiconductor has introduced a new family of CPE line drivers.
The EL2227C has a voltage noise specification of 1.9nV/rt-Hz and a current noise specification of only 1.2pA/rt-Hz.
It features a bandwidth of 115MHz and has a minimum gain of 2.
The EL2228C is specified with a voltage noise of 4.9nV/rt-Hz, a current noise of 1.2pA/rt-Hz, 80MHz bandwidth and is suitable for applications with a minimum gain of 1.
Both amplifiers operate on supplies from +/-2.5 to +/-12V with low power consumption.
These amplifiers are ideal choices for applications in medical imaging, such as ultrasound, where they can be used to amplify weak signals received from the image sensor.
They also find many uses in communications applications, such as DSL and optical networking, where they can be used to amplify very low voltage signals.
