LT6023/LT6023-1 Dual Micropower, 1.4V/s Precision Rail-to-Rail Output Amplifier FEATURES DESCRIPTION n Excellent Slew Rate to Power Ratio The LT 6023 is a low power, enhanced slew rate, precision n Slew Rate: 1.4V/s operational amplifier. The proprietary circuit topology of n Maximum Supply Current: 20A/Amplifier this amplifier gives excellent slew rate at low quiescent n Maximum Offset Voltage: 30V power dissipation without compromising precision or n High Dynamic Input Impedance settling time. In addition, proprietary input stage circuitry n Fast Recovery from Shutdown allows the input impedance to remain high during input n Maximum Input Bias Current: 3nA voltage steps as large as 5V. The combination of preci- n No Output Phase Inversion sion specs along with fast settling makes this part ideal n Gain Bandwidth Product: 40kHz for MUX applications. n Wide Specified Supply Range: 3V to 30V The low quiescent current of the LT6023 along with its n Operating Temperature Range: 40C to 125C ability to operate on supplies as low as 3V make it useful n Rail-to-Rail Outputs in portable systems. The LT6023-1 features a shutdown n DFN and MS8 Packages 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 APPLICATIONS DFN package. n Precision Signal Processing L, LT, LTC, LTM, Linear Technology, SmartMesh and the Linear logo are registered trademarks n DAC Amplifier and SoftSpan is a trademark of Linear Technology Corporation.
