Output Amplifier

TheLT®6020isalowpower,enhanced slewrate,precision

operational amplifier. The proprietary circuit topology of

this amplifier gives excellent slew rate at low quiescent

power dissipation without compromising precision or

settling time. In addition, unique input stage circuitry

allows the input impedance to remain high during input

voltage steps as large as 5V. The combination of preci-

sion specs along with fast settling makes this part ideal

for MUX applications.

The low quiescent current of the LT6020 along with its

ability to operate on supplies as low as 3V make it useful

in portable systems. The LT6020-1 features a shutdown

mode which reduces the typical supply current to 1.4μA.

The LT6020 is available in the small 8-lead DFN and 8-lead

MSOP packages. The LT6020-1 is available in a 10-lead

DFN package.
