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

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
