LT1806/LT1807 325MHz, Single/Dual, Rail-to-Rail Input Output, Distortion, Noise Precision Amps DESCRIPTION
LT®1806/LT1807 single/dual noise rail-to-rail input output unity-gain stable amps that feature 325MHz gain-bandwidth product, 140V/s slew rate 85mA output current. They optimized voltage, high performance signal conditioning systems. LT1806/LT1807 have very distortion 80dBc 5MHz, input referred noise voltage 3.5nV/Hz maximum offset voltage 550V that allows them used high performance data acquisition systems. LT1806/LT1807 have input range that includes both supply rails output that swings within 20mV either supply rail maximize signal dynamic range supply applications. LT1806/LT1807 maintain their performance supplies from 2.5V 12.6V specified supplies. inputs driven beyond supplies without damage phase reversal output. LT1806 available 8-pin package with standard pinout 6-pin SOT-23 package. LT1807 features standard dual pinout available 8-pin MSOP packages.These devices used plug-in replacements many amps improve input/output range performance.

Input Bias Current input bias current polarity depends given input common voltage which input stage operating. When input stage active, input bias currents flow input pins. When input stage activated, input bias current flows into input pins. Because input offset current less than input bias current, matching source resistances input pins will reduce total offset error. Output LT1806/LT1807 deliver large output current, short-circuit current limit around 85mA prevent damage device. Attention must paid keep junction temperature below absolute maximum rating 150°C (refer Power Dissipation section) when output continuously short-circuited. output amplifier reverse-biased diodes connected each supply. output forced beyond either supply, unlimited current will flow through these diodes. current transient limited hundred milliamps less, damage device will occur. Overdrive Protection When input voltage exceeds power supplies, pairs crossing diodes will prevent output from reversing polarity. input voltage exceeds either power supply 700mV, diode D1/D2 D3/D4 will turn keep output proper polarity. phase reversal protection perform properly, input current must limited less than 5mA. amplifier severely overdriven, external resistor should used limit overdrive current.

LT1806/LT1807 APPLICATIONS INFORMATION
LT1806/LT1807's input stages also protected against large differential input voltages 1.4V higher pair back-to-back diodes, D5/D8, that prevent emitter-base breakdown input transistors. current these diodes should limited less than 10mA when they active. worst-case differential input voltage usually occurs when input driven while output shorted ground unity gain configuration. addition, amplifier protected against strikes pins pair protection diodes, ESDD1 ESDD6, each that connected power supplies shown Figure Capacitive Load LT1806/LT1807 optimized high bandwidth distortion applications. They drive capacitive load about 20pF unity-gain configuration, more higher gain. When driving larger capacitive load, resistor should connected between output capacitive load avoid ringing oscillation. feedback should still taken from output that resistor will isolate capacitive load ensure stability. Graphs capacitive loads indicate transient response amplifier when driving capacitive load with specified series resistor. Feedback Components When feedback resistors used gain, care must taken ensure that pole formed feedback resistors total capacitance inverting input does degrade stability. instance, LT1806/LT1807 noninverting gain with resistors capacitance (part plus board) will probably ring transient response. pole formed 106MHz that will reduce phase margin degrees when crossover frequency amplifier around 70MHz. capacitor higher connected across feedback resistor will eliminate ringing oscillation. SHDN LT1806 SHDN reduce supply current less than 0.9mA. When SHDN pulled low, will generate signal power down device. left unconnected, internal pull-up resistor will keep part fully operating shown Figure output will high impedance during shutdown, turn-on turn-off time less than 100ns. Because input protected pair back back diodes, input signal will feed through output during shutdown mode amplitude signal between inputs larger than 1.4V.
