LT1800

1800f

80MHz, 25V/

µs Low Power

Rail-to-Rail Input and Output

Precision Op Amp

The LT

and output operational amplifier with excellent DC perfor-

mance. 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 sup-

ply 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 specified 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 SOT-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.
