DESCRIPTIO
Gain Bandwidth Product: 325MHz Slew Rate: 140V/s Wide Supply Range: 2.5V to 12V Large Output Current: 85mA Low Distortion, 5MHz: -80dBc Low Voltage Noise: 3.5nV/Hz Input Common Mode Range Includes Both Rails Output Swings Rail-to-Rail Input Offset Voltage (Rail-to-Rail): 550V Max Common Mode Rejection: 106dB Typ Power Supply Rejection: 105dB Typ Open-Loop Gain: 300V/mV Typ Power Down Pin SO-8 Package Operating Temperature Range -40C to 85C
The LT(R)1806 is a rail-to-rail input and output op amp that features a 325MHz gain bandwidth product, a 140V/s slew rate and a 85mA output current to fit the need for low voltage, high performance signal conditioning systems. The LT1806 has a very low distortion of - 80dBc at 5MHz, a low input referred noise voltage of 3.5nV/Hz and a maximum offset voltage of 550V that allows it to be used in high performance data acquisition systems. The LT1806 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 LT1806 maintains its performance for supplies from 2.5V to 12V 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 LT1806 is available in an 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 the 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 LT1806C/LT1806I are guaranteed functional over the temperature range of -40C and 85C. Note 5: The LT1806C is guaranteed to meet specified performance from 0C to 70C. The LT1806C is designed, characterized and expected to
meet specified performance from -40C to 85C but is not tested or QA sampled at these temperatures. The LT1806I 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. Note 9: Thermal resistance varies depending upon the amount of PC board metal attached to Pin 4 of the device. JA is specified for a 2500mm2 test board covered with 2 oz copper on both sides.

Single Supply Video Line Driver
The LT1806 is a wideband rail-to-rail op amp with high output current that allows it to drive video signals in low supply applications. The figure on the front page depicts a single supply video line driver with AC coupling to minimize the quiescent power dissipation. Resistors R1 and R2 are used to level-shift 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.
