The EL2003 and EL2033 are general
purpose monolithic unity gain buffers
featuring 100MHz, -3dB bandwidth
and 4ns small signal rise time. These buffers are capable of
delivering a ±100mA current to a resistive load and are
oscillation free into capacitive loads. In addition, the EL2003
and EL2033 have internal output short circuit current limiting
which will protect the devices under both a DC fault condition
and AC operation with reactive loads. The extremely fast
slew rate of 1200V/μs, wide bandwidth, and high output drive
make the EL2003 and EL2033 ideal choices for closed loop
buffer applications with wide band op amps. These same
characteristics and excellent DC performance make the
EL2003 and EL2033 excellent choices for open loop
applications such as driving coaxial and twisted pair cables.
The EL2003 and EL2033 are constructed using Elantec's
proprietary dielectric isolation process that produces PNP
and NPN transistors with essentially identical AC and DC
characteristics.
