Maximum power dissipation is a function of TJ(max), RθJA, and TA. The maximum allowable power dissipation at any allowable ambient temperature is PD = (TJ(max) − TA )/ RθJA. Operating at the absolute maximum TJ of 150°C can affect reliability. Due to variation in individual device electrical characteristics and thermal resistance, the built-in thermal overload protection may be activated at power levels slightly above or below the rated dissipation. The package thermal impedance is calculated in accordance with JESD 51-7. RθJC(top) and RθJC(bot)thermal impedances are calculated in accordance with MIL-STD-883 for LCCC and CDIP 6.5 Electrical Characteristics: LT1013C, ±15 V at specified free-air temperature, VCC± = ±15 V, VIC = 0 (unless otherwise noted) PARAMETER TA (1) TEST CONDITIONS RS = 50 Ω MIN 25°C TYP (2) MAX 60 300 VIO Input offset voltage αVIO Temperature coefficient of input offset voltage Full range 0.4 Long-term drift of input offset voltage 25°C 0.5 25°C 0.2 IIO Input offset current IIB Input bias current VICR Common-mode input voltage range Recommended range VOM Maximum peak output voltage swing RL = 2 kΩ AVD Large-signal differential voltage amplification Full range –15 Full range Full range –15 13 ±12.5 ±14 0.5 0.2 1.2 7 Full range 0.7 VIC = −15 V to 13.5 V 25°C 97 VIC = −14.9 V to 13 V Full range 94 Supply-voltage rejection ratio (ΔVCC/ΔVIO) VCC+ = ±2 V to ±18 V Channel separation VO = ±10 V, RL = 2 kΩ –30 13.5 25°C kSVR 1.5 –15 25°C Common-mode rejection ratio µV/mo 25°C ±12 CMRR µV/°C –38 Full range VO = ±10 V, RL = 2 kΩ 2.5 2.8 25°C VO = ±10 V, RL = 600 Ω µV 400 Full range 25°C UNIT 25°C 100 Full range nA nA V V V/µV 114 dB 117 dB 97 25°C 120 137 dB rid Differential input resistance 25°C 70 300 MΩ ric Common-mode input resistance 25°C 4 GΩ ICC Supply current per amplifier 25°C 0.35 (1) (2) Full range 0.55 0.7 mA Full range is 0°C to 70°C.

There are no side effects from active VIO correction used by other op amps. The LT1013x has built-in protection for input voltage below VCC–. However, an external resistance must be add to protect the LT1013x from input voltage greater than VCC+. 7.2 Functional Block Diagram VCC+ 9 kΩ 9 kΩ 1.6 kΩ 1.6 kΩ 100 Ω 1.6 kΩ 800 Ω 1 kΩ Q36 Q5 Q6 Q13 Q16 Q14 Q15 Q32 Q35 Q30 J1 Q3 Q37 Q25 Q4 Q33 3.9 kΩ Q1 2.4 kΩ Q27 21 pF 400 Ω Q41 Q26 2.5 pF 14 kΩ 18 Ω Q38 IN− OUT Q21 Q2 Q28 Q39 400 Ω IN+ Q12 4 pF Q18 Q22 Q31 Q40 Q29 Q10 Q11 Q19 Q9 Q7 Q34 2 kΩ Q8 10 pF Q17 10 pF Q23 Q20 75 pF 5 kΩ 5 kΩ Q24 2 kΩ 2 kΩ 42 kΩ 600 Ω 30 Ω 1.3 kΩ VCC− Component values are nominal. Copyright © 2016, Texas Instruments Incorporated 7.3 Feature Description 7.3.1 Input Resistors For voltages less than VCC–, a pair of 400-Ω resistors limit input current. These resistors have parasitic diodes to VCC+. Therefore, external series resistance is needed if input voltage exceed VCC+ 7.3.2 Output Stage High output is provided by Q33 emitter for low output impedance. Q26 provides active current limiting for sourcing current. Low output is provided by Q34 collector for lower output voltage near VCC– rail. Q24 provides active current limiting for sinking current.

Typical supply current at this voltage is 290 µA; therefore, power dissipation is only 1 mW per amplifier. 7.3.4 Output Phase Reversal Protection The LT1013x is fully specified for single-supply operation (VCC− = 0). The common-mode input voltage range includes ground, and the output swings to within a few millivolts of ground. Furthermore, the LT1013x has specific circuitry that addresses the difficulties of single-supply operation, both at the input and at the output. At the input, the driving signal can fall below 0 V, either inadvertently or on a transient basis. If the input is more than a few hundred millivolts below ground, the LT1013x is designed to deal with the following two problems that can occur: 1. On many other operational amplifiers, when the input is more than a diode drop below ground, unlimited current flows from the substrate (VCC− terminal) to the input, which can destroy the unit. On the LT1013x, the 400-Ω resistors in series with the input protect the device, even when the input is 5 V below ground. 2. When the input is more than 400 mV below ground (at TA = 25°C), the input stage of similar operational amplifiers saturates, and phase reversal occurs at the output. This can cause lockup in servo systems. Because of unique phase-reversal protection circuitry (Q21, Q22, Q27, and Q28), the LT1013x outputs do not reverse, even when the inputs are at −1.5 V (see Figure 24). This phase-reversal protection circuitry does not function when the other operational amplifier on the LT1013x is driven hard into negative saturation at the output. Phase-reversal protection does not work on amplifier 1 when amplifier 2 output is in negative saturation nor on amplifier 2 when amplifier 1 output is in negative saturation. At the output, other single-supply designs either cannot swing to within 600 mV of ground or cannot sink more than a few micro amperes while swinging to ground. The all-npn output stage of the LT1013x maintains its low output resistance and high-gain characteristics until the output is saturated. In dual-supply operations, the output stage is free of crossover distortion. 5 4 3 2 1 0 −1 −2 VO VO − Output Voltage − V 5 VO VO − Output Voltage − V VI(PP) V I(PP) − Input Voltage − V 5 4 3 2 1 0 3 2 1 0 −1 −1 (a) VI(PP) = −1.5 V TO4.5 V 4 (b) OUTPUT PHASE REVERSAL EXHIBITED BY LM358 (c) NO PHASE REVERSAL EXHIBITED BY LT1013 Figure 24.

TI’s customers are responsible for determining suitability of components for their purposes. Customers should validate and test their design implementation to confirm system functionality. 8.1 Application Information The LT1013x operational amplifiers are useful in a wide range of signal conditioning applications where high DC accuracy is needed. 8.2 Typical Application A typical application for an operational amplifier in an inverting amplifier. This amplifier takes a positive voltage on the input and makes it a negative voltage of the same magnitude. In the same manner, it also makes negative voltages positive. RF RI Vsup+ VOUT VIN + VsupCopyright © 2016, Texas Instruments Incorporated Figure 27. Application Schematic 8.2.1 Design Requirements The supply voltage must be chosen such that it is larger than the input voltage range and output range. For instance, this application scales a signal of ±0.5 V to ±1.8 V. Setting the supply at ±12 V is sufficient to accommodate this application. 8.2.2 Detailed Design Procedure Determine the gain required by the inverting amplifier using Equation 1 and Equation 2: (1) (2) Once the desired gain is determined, choose a value for RI or RF. Choosing a value in the kΩ range is desirable because the amplifier circuit will use currents in the milliamp range. This ensures the part does not draw too much current. This example chooses 10 kΩ for RI, which means 36 kΩ is used for RF. This was determined by Equation 3.

Input and Output Voltages of the Inverting Amplifier 9 Power Supply Recommendations CAUTION Supply voltages larger than 44 V for a single supply, or outside the range of ±22 V for a dual supply can permanently damage the device (see Absolute Maximum Ratings). Place 0.1-µF bypass capacitors close to the power-supply pins to reduce errors coupling in from noisy or high impedance power supplies. For more detailed information on bypass capacitor placement, see Layout. 10 Layout 10.1 Layout Guidelines For best operational performance of the device, use quality PCB layout practices, including: • Noise can propagate into analog circuitry through the power pins of the circuit as a whole, as well as the operational amplifier. Bypass capacitors are used to reduce the coupled noise by providing low impedance power sources local to the analog circuitry. – Connect low-ESR, 0.1-µF ceramic bypass capacitors between each supply pin and ground, placed as close to the device as possible. A single bypass capacitor from V+ to ground is applicable for singlesupply applications. • Separate grounding for analog and digital portions of circuitry is one of the simplest and most effective methods of noise suppression. One or more layers on multilayer PCBs are usually devoted to ground planes. A ground plane helps distribute heat and reduces EMI noise pickup. Make sure to physically separate digital and analog grounds, paying attention to the flow of the ground current. • Run the input traces as far away from the supply or output traces as possible to reduce parasitic coupling. If it is not possible to keep them separate, it is much better to cross the sensitive trace perpendicular as opposed to in parallel with the noisy trace. • Place the external components as close to the device as possible. Keeping RF and RG close to the inverting input minimizes parasitic capacitance, as shown in Layout Guidelines. • Keep the length of input traces as short as possible. Always remember that the input traces are the most sensitive part of the circuit. • Consider a driven, low-impedance guard ring around the critical traces. A guard ring can significantly reduce leakage currents from nearby traces that are at different potentials.
