LT1809IS8#PBF

The LT1809/LT1810 are single/dual low distortion rail-to-rail input and output op amps with a 350V/μs slew rate. These amplifiers have a –3dB bandwidth of 320MHz at unity-gain, a gain-bandwidth product of 180MHz (AV ≥ 10) and an 85mA output current to fit the needs of low voltage, high performance signal conditioning systems. The LT1809/LT1810 have 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 LT1809/LT1810 have very low distortion (–90dBc) up to 5MHz that allows them to be used in high performance data acquisition systems. The LT1809/LT1810 maintain their performance for supplies from 2.5V to 12.6V and are specified at 3V, 5V and ±5V supplies. The inputs can be driven beyond the supplies without damage or phase reversal of the output. The LT1809 is available in the 8-pin SO package with the standard op amp pinout and the 6-pin SOT-23 package. The LT1810 features the standard dual op amp pinout and is available in 8-pin SO and MSOP packages. These devices can be used as a plug-in replacement for many op amps to improve input/output range and performance.
