The LT
®
6020 is a low power, enhanced slew rate, 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.
