LT1809/LT1810 Single/Dual 180MHz, 350V/µs Rail-to-Rail Input and Output Low Distortion Op Amps
FEATURES DESCRIPTION
n
–3dB Bandwidth: 320MHz, AV = 1
The LT®1809/LT1810 are single/dual low distortion rail-to- n
Gain-Bandwidth Product: 180MHz, AV ≥ 10
rail input and output op amps with a 350V/μs slew rate. n
Slew Rate: 350V/μs
These amplifi 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 (AV ≥ 10) n
Large Output Current: 85mA
and an 85mA output current to fi 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 Open-Loop Gain: 100V/mV Typ The LT1809/LT1810 have very low distortion (–90dBc) up n Shutdown Pin: LT1809 to 5MHz that allows them to be used in high performance n Single in 8-Pin SO and 6-Pin SOT-23 Packages data acquisition systems. n Dual in 8-Pin SO and MSOP Packages The LT1809/LT1810 maintain their performance for supplies n Operating Temperature Range: –40°C to 85°C from 2.5V to 12.6V and are specifi ed at 3V, 5V and ± 5V n Low Profi 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 Amplifi ers can be used as a plug-in replacement for many op amps n Video Line Driver to improve input/output range and performance.
