DESCRIPTION
The LT^®6023 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, proprietary 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 LT6023 along with its
ability to operate on supplies as low as 3V make it useful
in portable systems. The LT6023-1 features a shutdown
mode which reduces the typical supply current to 800nA.
The LT6023 is available in the small 8-lead DFN and 8-lead
MSOP packages. The LT6023-1 is available in a 10-lead
DFN package.
