When driving heavy loads, additional 4.7F electrolytic capacitor should used. When using split supplies, same true negative supply pin. LT1783 protected against reverse-battery voltages 18V. event reverse-battery condition occurs, supply current less than 1nA. Inputs LT1783 input stages, (see Simplified Schematic), resulting three distinct operating regions shown Input Bias Current Common Mode typical performance curve. input voltages about 0.8V more below input stage active input bias current typically -40nA. When input common mode voltage within 0.5V positive rail, stage operating input bias current typically 80nA. Increases temperature will cause voltage which operation switches from input stage input stage move towards input offset voltage stage untrimmed typically 1.8mV. Schottky diode collector input transistors, along with special geometries these transistors, allow LT1783 operate with either both inputs above about 0.3V above input transistor fully saturated input bias current typically room temperature. input offset voltage typically 1.8mV when operating above LT1783 will operate with inputs above regardless inputs protected against excursions much below internal resistor series with each input diode from input negative supply. input stage LT1783 incorporates phase reversal protection prevent output from phase reversing inputs below There clamping diodes between inputs maximum differential input voltage 18V. Output output LT1783 swing within 60mV positive rail with load within negative rail with load. When monitoring input voltages within 60mV positive rail within negative rail, gain should taken keep output from clipping. LT1783 sink source over 30mA supplies, sourcing current reduced 10mA total supplies noted Electrical Characteristics. LT1783 internally compensated drive least 400pF capacitance under output loading conditions. 0.22F capacitor series with resistor between output ground will compensate these amplifiers larger capacitive loads, 10,000pF output currents. Distortion There main contributors distortion amps: output crossover distortion output transitions from sourcing sinking current, distortion caused nonlinear common mode rejection. operating inverting, there common mode induced distortion. operating input stage (input within 0.8V V+), CMRR very good, typically 100dB. When LT1783 switches between input stages, there significant nonlinearity CMRR. Lower load resistance increases output crossover distortion effect input stage transition distortion. lowest distortion, LT1783 should operated single supply, with output always sourcing current with input voltage swing between ground 0.8V).
