These amplifiers are reverse supply protected; they draw no current for reverse supply up to 8V. The input range of the LT49/ LT49 includes both supplies and the output swings to both supplies. nlike most micropower op amps, the LT49/ LT49 can drive heavy loads; their rail-to-rail outputs drive ma. The are unity-gain stable and drive all capacitive loads up to,pf when optional.22µf and Ω compensation is used. The have a unique input stage that operates and remains high impedance when above the positive supply. The inputs take 44V both differential and common mode even when operating on a 3V supply. Built-in resistors protect the inputs for faults below the negative supply up to 22V. There is no phase reversal of the output for inputs 22V below V or 44V above V, independent of V. The LT49 dual op amp is available in the 8-pin SO and PDIP packages. The quad LT49 is available in the 4-pin SO and PDIP packages., LTC and LT are registered trademarks of Linear Technology Corporation.

8 APPLICATIONS INFORMATION Supply Voltage 8 W The positive supply pin of the should be bypassed with a small capacitor (about.µf) within an inch of the pin. When driving heavy loads an additional 4.7µF electrolytic capacitor should be used. When using split supplies, the same is true for the negative supply pin. The are protected against reverse battery voltages up to 8V. In the event a reverse battery condition occurs, the supply current is less than na. The can be shut down by removing V. In this condition the input bias current is less than.na, even if the inputs are 44V above the negative supply. When operating the on total supplies of V or more, the supply must not be brought up faster than µs. This is especially true if low ESR bypass capacitors are used. A series RLC circuit is formed from the supply lead inductance and the bypass capacitor. 5Ω of resistance in the supply or the bypass capacitor will dampen the tuned circuit enough to limit the rise time. Inputs The have two input stages, NPN and PNP (see the Simplified Schematic), resulting in three distinct operating regions as shown in the Input Bias Current vs Common Mode typical performance curve. For input voltages about.8v or more below V, the PNP input stage is active and the input bias current is typically 4nA. When the input voltage is about.5v or less from V, the NPN input stage is operating and the input bias current is typically 8nA. Increases in temperature will cause the voltage at which operation switches from the PNP stage to the NPN stage to move towards V. The input offset voltage of the NPN stage is untrimmed and is typically µv. A Schottky diode in the collector of each NPN transistor of the NPN input stage allows the to operate with either or both of its inputs above V. At about.3v above V the NPN input transistor is fully saturated and the input bias current is typically 4µA at room temperature. The input offset voltage is typically µv when operating above V. The will operate with its inputs 44V above V regardless of V. The inputs are protected against excursions as much as 22V below V by an internal k resistor in series with each input and a diode from the input to the negative supply. There is no output phase reversal for inputs up to 22V below V. There are no clamping diodes between the inputs and the maximum differential input voltage is 44V. Output The output voltage swing of the is affected by input overdrive as shown in the typical performance curves. When monitoring voltages within mv of either rail, gain should be taken to keep the output from clipping. The output of the can be pulled up to 8V beyond V with less than na of leakage current, provided that V is less than.5v. The normally reverse-biased substrate diode from the output to V will cause unlimited currents to flow when the output is forced below V. If the current is transient and limited to ma, no damage will occur. The is internally compensated to drive at least pf of capacitance under any output loading conditions. A.22µF capacitor in series with a Ω resistor between the output and ground will compensate these amplifiers for larger capacitive loads, up to,pf, at all output currents. Distortion There are two main contributors of distortion in op amps: output crossover distortion as the output transitions from sourcing to sinking current and distortion caused by nonlinear common mode rejection. Of course, if the op amp is operating inverting there is no common mode induced distortion. When the LT49 switches between input stages there is significant nonlinearity in the CMRR. Lower load resistance increases the output crossover distortion, but has no effect on the input stage transition distortion. For lowest distortion the should be operated single supply, with the output always sourcing current and with the input voltage swing between ground and (V.8V). See the Typical Performance Characteristics curves.

9 APPLICATIONS INFORMATION W Gain The open-loop gain is almost independent of load when the output is sourcing current. This optimizes performance in single supply applications where the load is returned to ground. The typical performance photo of Open-Loop Gain for various loads shows the details.
