The LT(R)1809 is a low distortion rail-to-rail input and output op amp with a 350V/s 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. 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. 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.

Note 1: Absolute Maximum Ratings are those values beyond which the life of a device may be impaired. Note 2: The inputs are protected by back-to-back diodes. If the differential input voltage exceeds 1.4V, the input current should be limited to less than 10mA. Note 3: A heat sink may be required to keep the junction temperature below the absolute maximum rating when the output is shorted indefinitely. Note 4: The LT1809C/LT1809I are guaranteed functional over the operating temperature range of - 40oC and 85oC.
Note 5: The LT1809C is guaranteed to meet specified performance from 0C to 70C. The LT1809C is designed, characterized and expected to meet specified performance from - 40C to 85C but is not tested or QA sampled at these temperatures. The LT1809I is guaranteed to meet specified performance from - 40C to 85C. Note 6: Minimum supply voltage is guaranteed by power supply rejection ratio test. Note 7: Output voltage swings are measured between the output and power supply rails. Note 8: This parameter is not 100% tested.

TYPICAL APPLICATIO
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. The gain of two is set up with R3 and R4 to restore the signal at VOUT which is attenuated by 6dB due to the

matching of the 75 line with the back-terminated resistor, R5. 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.
