Rail-to-Rail Input and Output
DESCRIPTION
The LT
output operational amplifi er with excellent DC performance.
The LT1800 features reduced supply current, lower input
offset voltage, lower input bias current and higher DC gain
than other devices with comparable bandwidth.
The LT1800 has an input range that includes both supply
rails and an output that swings within 20mV of either
supply rail to maximize the signal dynamic range in low
supply applications.
The LT1800 maintains its performance for supplies from
2.3V to 12.6V and is specifi ed at 3V, 5V and ±5V supplies.
The inputs can be driven beyond the supplies without
damage or phase reversal of the output.
The LT1800 is available in the 8-pin SO package with
the standard op amp pinout and in the 5-pin TSOT-23
package. For dual and quad versions of the LT1800, see
the LT1801/LT1802 data sheet. The LT1800 can be used
as a plug-in replacement for many op amps to improve
input/output range and performance.
