Product Details

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.

Design Tools

Analog Filter Wizard

Use the Analog Filter Wizard to design low-pass, high-pass, or band-pass filters with actual op amps in minutes. As you progress through the design process, you can observe the characteristics of your filter design from ideal specifications to real world circuit behavior. Quickly evaluate the tradeoffs in op amp specifications - including gain-bandwidth, noise, and supply current – to determine the best filter design for your requirements.

Design Resources

ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and reliability. We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well.  "Zero defects" for shipped products is always our goal.
