Dual Micropower, 1.4V/μs Precision Rail-to-Rail Output Amplifier

The LT6023 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 precision 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.
