General Description

The EL2003C and EL2033C 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 addi-

tion, the EL2003C and EL2033C 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 EL2003C and EL2033C ideal choices for closed loop buffer appli-

cations with wide band op amps. These same characteristics and

excellent DC performance make the EL2003C and EL2033C excellent

choices for open loop applications such as driving coaxial and twisted

pair cables.

The EL2003C and EL2033C are constructed using Elantec's propri-

etary dielectric isolation process that produces PNP and NPN

transistors with essentially identical AC and DC characteristics.
