n
Excellent Slew Rate to Power Ratio
The LT®6020 is a low power, enhanced slew rate, precision n
Slew Rate: 5V/μs
operational amplifier. The proprietary circuit topology of n
Maximum Supply Current: 100μA/Amplifier
this amplifier gives excellent slew rate at low quiescent n
Maximum Offset Voltage: 30μV
power dissipation without compromising precision or n
Maximum Offset Voltage Drift: 0.5μV/°C
settling time. In addition, unique input stage circuitry n
High Dynamic Input Impedance
allows the input impedance to remain high during input n
Fast Recovery from Shutdown
voltage steps as large as 5V. The combination of preci- n
Maximum Input Bias Current: 3nA
sion specs along with fast settling makes this part ideal n
No Output Phase Inversion
for MUX applications. n Gain Bandwidth Product: 400kHz The low quiescent current of the LT6020 along with its n Wide Specified Supply Range: 3V to 30V ability to operate on supplies as low as 3V make it useful n Operating Temperature Range: –40°C to 125°C in portable systems. The LT6020-1 features a shutdown n DFN and MS8 Packages mode which reduces the typical supply current to 1.4μA. n Rail-to-Rail Outputs The LT6020 is available in the small 8-lead DFN and 8-lead MSOP packages. The LT6020-1 is available in a 10-lead
