LT1809/LT1810 Single/Dual 180MHz, 350V/s Rail-to-Rail Input and Output Low Distortion Op Amps FEATURES DESCRIPTION n 3dB Bandwidth: 320MHz, A = 1 The LT 1809/LT1810 are single/dual low distortion rail-to- V n Gain-Bandwidth Product: 180MHz, A 10 rail input and output op amps with a 350V/s slew rate. V n Slew Rate: 350V/s These ampli ers have a 3dB bandwidth of 320MHz at n Wide Supply Range: 2.5V to 12.6V unity-gain, a gain-bandwidth product of 180MHz (A 10) V n Large Output Current: 85mA and an 85mA output current to t the needs of low voltage, n Low Distortion, 5MHz: 90dBc high performance signal conditioning systems. n Input Common Mode Range Includes Both Rails The LT1809/LT1810 have an input range that includes n Output Swings Rail-to-Rail both supply rails and an output that swings within 20mV n Input Offset Voltage, Rail-to-Rail: 2.5mV Max of either supply rail to maximize the signal dynamic range n Common Mode Rejection: 89dB Typ in low supply applications. n Power Supply Rejection: 87dB Typ n The LT1809/LT1810 have very low distortion (90dBc) up Open-Loop Gain: 100V/mV Typ n to 5MHz that allows them to be used in high performance Shutdown Pin: LT1809 n data acquisition systems. Single in 8-Pin SO and 6-Pin SOT-23 Packages n Dual in 8-Pin SO and MSOP Packages The LT1809/LT1810 maintain their performance for supplies n Operating Temperature Range: 40C to 85C from 2.5V to 12.6V and are speci ed at 3V, 5V and 5V n Low Pro le (1mm) SOT-23 (ThinSOT) Package supplies. The inputs can be driven beyond the supplies without damage or phase reversal of the output. APPLICATIONS The LT1809 is available in the 8-pin SO package with the n Driving A/D Converters standard op amp pinout and the 6-pin SOT-23 package. n Low Voltage Signal Processing The LT1810 features the standard dual op amp pinout and n Active Filters is available in 8-pin SO and MSOP packages. These devices n Rail-to-Rail Buffer Ampli ers can be used as a plug-in replacement for many op amps n Video Line Driver to improve input/output range and performance.
