LT1812 APPLICATIONS INFORMATION
Layout Passive Components LT1812 amplifier more tolerant less than ideal layouts than other high speed amplifiers. maximum performance (for example, fast settling) ground plane, short lead lengths RF-quality bypass capacitors (0.01F 0.1F). high drive current applications, bypass capacitors tantalum). parallel combination feedback resistor gain setting resistor inverting input combine with input capacitance form pole that cause peaking even oscillations. feedback resistors greater than used, parallel capacitor value CIN/RF should used cancel input pole optimize dynamic performance. applications where noise gain large feedback resistor used, should greater than equal CIN. example would I-to-V converter. Input Considerations Each LT1812 amplifier inputs base transistor whose base currents opposite polarity provide first-order bias current cancellation. Because variation matching beta, polarity input bias current positive negative. offset current does depend beta matching well controlled. balanced source resistance each input recommended applications where accuracy must maximized. inputs withstand differential input voltages without damage need clamping source resistance protection. device should used comparator because with sustained differential inputs, excessive power dissipation result. Capacitive Loading LT1812 stable with 1000pF capacitive load, which outstanding 100MHz amplifier. This accomplished sensing load induced output pole adding compensation amplifier gain node. capacitive load increases, both bandwidth phase margin decrease there will peaking frequency domain transient response. Coaxial cable driven directly, best pulse fidelity, resistor value equal characteristic impedance cable (i.e., should placed series with output. other cable should terminated with same value resistor ground. Slew Rate slew rate proportional differential input voltage. Highest slew rates therefore seen lowest gain configurations. example, output step gain 0.5V input step, whereas unity gain there input step. LT1812 tested slew rate gain Lower slew rates occur higher gain configurations. Shutdown LT1812 shutdown (SHDN, conserving power. When this open biased least above negative supply, part operates normally. When pulled down supply current drops about 50A. Typically, turn-off delay turn-on delay 0.5s. current SHDN also typically 50A. shutdown mode, amplifier output isolated from inputs, LT1812 shutdown feature cannot used multiplexing applications. typical shutdown current exclusive output (load) current. order prevent load current (and maximize power savings), either load needs disconnected, input signal needs Even shutdown mode, LT1812 still drive significant current into load. example, configuration, when driven with input, LT1812 drives into load. takes about 500s load current reach this value.

Complementary followers form output stage that buffers gain node from load. bandwidth input resistor capacitance high impedance node. slew rate determined current available charge gain node capacitance. This current differential input voltage divided slew rate proportional input. Highest slew rates therefore seen lowest gain configurations. network across output stage bootstrapped when amplifier driving light moderate load effect under normal operation. When driving capacitive loads value resistive load) network incompletely bootstrapped adds compensation high impedance node. added capacitance slows down amplifier which improves phase margin moving unity-gain cross away from pole formed output impedance capacitive load. zero created combination adds phase ensure that total phase does exceed degrees (zero phase margin) amplifier remains stable. this way, LT1812 stable with 1000pF capacitive loads unity gain, even higher capacitive loads higher closed-loop gain configurations.
