High Accuracy Fast Buffer
Features
Low input current 50 pA Low offset and drift 2 mV 25 mV C High slew rate 1500 V ms Fast rise and fall time 2 5 ns High input resistance 1000 GX Bandwidth 140 MHz Pin compatible with ELH0033 MIL-STD-883 Revision C devices manufactured in U S A
General Description
The EL2005 is a high-speed FET input buffer similar to ELH0033 and EL2004 but with input specifications significantly improved over the previous types The input stage employs a cascode configuration to maintain constant input characteristics over the full g 10V input range The input looks like a 3 pF capacitor to ground in almost all cases since the DC bias current is constant with input voltage In sample and hold circuits this results in an order of magnitude improvement in hold characteristics Input offset voltage and offset voltage drift are also improved a factor of two over previous types These excellent DC characteristics are complemented by a wide 140 MHz bandwidth while the 1500 V ms slew rate and excellent phase linearity of the ELH0033 family are preserved allowing direct plug-in replacement for upgraded performance (For even faster operation see EL2004 ) 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
Advantages
No input loading Input current independent of input voltage Eliminates offset adjustments Drives cables directly
