High Accuracy Fast Buffer

Applications Information Contd

Operation within an Op Amp Loop

The EL2005 may be used as a current booster or

isolation buffer within a closed loop with op

amps such as the ELH0032 and HA2500 and

HA2600 series An isolation resistor of 47X

should be used between the op amp output and

the input of EL2005 The wide bandwidth and

high slew rates of the EL2005 assure that the

loop has the characteristics of the op amp and

that additional rolloff is not required

Burn-In Circuit

Hardware

In order to utilize the full drive capabilities of the

EL2005 it should be mounted with a heatsink

particularly for extended temperature operation

The case is isolated from the circuit and may be

connected to system chassis

IMPORTANT

Power supply bypassing is necessary to prevent

oscillation with the EL2005 in all circuits Low

inductance ceramic disc capacitors with the

shortest practical lead lengths must be connected

from each supply lead (within to of the

device package) to a ground plane Capacitors

should be one or two 0 1 mF in parallel adding a

4 7 mF solid tantalum capacitor will help in trou-

blesome instances
