LT1815/LT1816/LT1817 APPLICATIONS INFORMATION
Layout Passive Components with high speed amplifiers, LT1815/LT1816/ LT1817 require some attention board layout. ground plane recommended trace lengths should minimized, especially negative input lead. ESL/ESR bypass capacitors should placed directly positive negative supply (0.01F ceramics recommended). high drive current applications, additional tantalums should added. 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: 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 inputs LT1815/LT1816/LT1817 amplifiers connected base bipolar transistor parallel. base currents opposite polarity provide first-order bias current cancellation. variation matching beta, polarity input bias current positive negative. offset current, however, does depend beta matching tightly controlled. Therefore, balanced source resistance each input recommended applications where accuracy must maximized. example, with source resistance each input, 800nA maximum offset current results only extra offset, while without balance maximum input bias current could result 0.8mV offset contribution. inputs withstand differential input voltages without damage without needing clamping series resistance protection. This differential input voltage generates large internal current 80mA), which results high slew rate. normal transient closed-loop operation, this does increase power dissipation significantly because duty cycle transient inputs. Sustained differential inputs, however, will result excessive power dissipation therefore this device should used comparator. Capacitive Loading LT1815/LT1816/LT1817 optimized high bandwidth distortion applications. They drive capacitive load 10pF unity-gain configuration more with 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. Slew Rate slew rate LT1815/LT1816/LT1817 proportional differential input voltage. Therefore, highest slew rates seen lowest gain configurations. example, output step gain 0.5V input step, whereas unity gain there input step. LT1815/LT1816/LT1817 tested slew rate gain Lower slew rates occur higher gain configurations. Programmable Supply Current (LT1815/LT1816A) order operate LT1815S6 LT1816A full speed (and full supply current), connect ISET negative supply through resistance less. adjust program supply current speed LT1815S6 LT1816A, connect external resistor (RSET) between ISET negative supply, shown Figure amplifiers fully functional with RSET 40k. Figures show gain bandwidth supply current vary with value programming resistor RSET. addition, Electrical Characteristics section data sheet specifies maximum supply current offset voltage, well minimum gain bandwidth output current maximum RSET value 40k.
