LT1800 General Description


The LT®1800 is a low power, high speed rail-to-rail inputand output operational amplifier with excellent DC perfor-mance. The LT1800 features reduced supply current, lowerinput offset voltage, lower input bias current and higherDC gain than other devices with comparable bandwidth.

The LT1800 has an input range that includes both supplyrails and an output that swings within 20mV of either sup-ply rail to maximize the signal dynamic range in low supplyapplications.

The LT1800 maintains its performance for supplies from2.3V to 12.6V and is specified at 3V, 5V and ±5V supplies.

The inputs can be driven beyond the supplies withoutdamage or phase reversal of the output.

The LT1800 is available in the 8-pin SO package with thestandard 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-inreplacement for many op amps to improve input/outputrange and performance.
