Final Electrical Specifications LT1809 180MHz, 350V/µs Rail-to-Rail Input and Output Low Distortion Op Amp January 2000 U DESCRIPTIO FEATURES ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ The LT®1809 is a low distortion rail-to-rail input and output op amp with a 350V/µs slew rate. The amplifier has 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. –3dB Bandwidth: 320MHz, AV = 1 Gain-Bandwidth Product: 180MHz, AV ≥ 10 Slew Rate: 350V/µs Wide Supply Range: 2.5V to 12.6V Large Output Current: 85mA Low Distortion, 5MHz: – 90dBc Input Common Mode Range Includes Both Rails Output Swings Rail-to-Rail Input Offset Voltage, Rail-to-Rail: 2.5mV Max Common Mode Rejection: 89dB Typ Power Supply Rejection: 87dB Typ Open-Loop Gain: 100V/mV Typ Shutdown Pin 8-Pin SO-8 Package Operating Temperature Range – 40°C to 85°C The LT1809 has 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 has very low distortion (–90dBc) up to 5MHz that allows it to be used in high performance data acquisition systems. The LT1809 maintains its performance for supplies from 2.5V to 12.6V and is specified at 3V, 5V and ±5V supplies. The inputs can be driven beyond the supplies without damage or phase reversal of the output. U APPLICATIO S ■ ■ ■ ■ Active Filters Rail-to-Rail Buffer Amplifiers Driving A/D Converters Low Voltage Signal Processing Video Line Driver The LT1809 is available in the 8-pin SO package with the standard op amp pinout. This device can be used as a plugin replacement for many op amps to improve input/output range and performance. , LTC and LT are registered trademarks of Linear Technology Corporation.

The back termination will eliminate any reflection of the signal that comes from the load. The input termination resistor, RT, is optional—it is used only if matching of the incoming line is necessary. The values of C1, C2 and C3 are selected to minimize the droop of the luminance signal. In some less stringent requirements, the value of capacitors could be reduced. Single Supply Video Line Driver The LT1809 is a wideband rail-to-rail op amp with high output current that allows it to drive video signals in low supply applications. Figure 1 depicts a single supply video line driver with AC coupling to minimize the quiescent power dissipation. Resistors R1 and R2 are used to levelshift the input and output to provide the largest signal swing.
