Current Amplifier
Features
400 mA pulsed output current DC to 30 MHz bandwidth 200 V ms slew rate Low harmonic distortion High input impedance 400 kX Low output impedance 6X High power efficiency Operation from g 5V to g 20V Output voltage swing approaches supply voltage MIL-STD-883 devices manufactured in U S A
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 The ELH0002 is specified for operation over the b 55 C to a 125 C military temperature range Elantec facilities comply with MIL-I-45208A and are MILSTD-1772 certified Elantec’s Military devices comply with MIL-STD-883B Revision C and are manufactured in our rigidly controlled ultra-clean facilities in Milpitas California For additional information on Elantec’s Quality and Reliability Assurance Policy and procedures request brochure QRA-1
