LT6023/LT6023-1 Dual Micropower, 1.4V/µs 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/μs
operational amplifier. The proprietary circuit topology of n
Maximum Supply Current: 20μA/Amplifier
this amplifier gives excellent slew rate at low quiescent n
Maximum Offset Voltage: 30μV
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: –40°C to 125°C 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
