These amplifiers operate on single and split supplies with a total voltage of 3V to 50V and draw only 315µA per amplifier. They are reverse battery protected, drawing very little current for reverse supplies up to 50V. The Over-The-Top® input stage of the LT6015/LT6016/ LT6017 is designed to provide added protection in tough environments. The input common mode range extends from V– to V+ and beyond: these amplifiers operate with inputs up to 76V above V– independent of V+. Internal resistors protect the inputs against transient faults up to 25V below the negative supply. The LT6015/LT6016/ LT6017 can drive loads up to 25mA and are unity-gain stable with capacitive loads as large as 200pF. Optional external compensation can be added to extend the capacitive drive capability beyond 200pF. The LT6015 is offered in a 5-lead SOT package. The LT6016 dual op amp is available in an 8-lead MSOP package. The LT6017 is offered in a 22-pin leadless DFN package.

Exposure to any Absolute Maximum Rating condition for extended periods may affect device reliability and lifetime. Note 2: Voltages applied are with respect to V–. The inputs are tested to the Absolute Maximum Rating by applying –25V (relative to V–) to each input for 10ms. In general, faults capable of sinking current from either input should be current limited to under 10mA. See the Applications Information section for more details. Note 3: A heat sink may be required to keep the junction temperature below absolute maximum. This depends on the power supply voltage and how many amplifiers are shorted. Note 4: The LT6015I/LT6016I/LT6017I are guaranteed functional over the oper ating temperature range of –40°C to 85°C.

Junction temperatures greater than 125°C will promote accelerated aging. The LT6015/LT6016/LT6017 has a demonstrated typical performance beyond 1000 hours at TJ = 150°C. Note 5: The LT6015I/LT6016I/LT6017I are guaranteed to meet specified performance from –40°C to 85°C. The LT6015H/LT6016H/LT6017H are guaranteed to meet specified performance from –40°C to 125°C. The LT6015MP/LT6016MP/LT6017MP are guaranteed to meet specified performance with junction temperature ranging from –55°C to 150°C. Note 6: Test accuracy is limited by high speed test equipment repeatability. Bench measurements indicate the input offset current in the Over-The-Top configuration is typically controlled to under ±50nA at 25°C and ±150nA over temperature. Note 7: The Reverse Supply voltage is tested by pulling 25μA/Amplifier out of the V+ pin while measuring the V+ pin’s voltage with both inputs and V– grounded, verifying V+ < –50V. 601567ff For more

bypassed with a small capacitor (typically 0.1μF) as close to the supply pins as possible. When driving heavy loads an additional 4.7μF electrolytic capacitor should be added. When using split supplies, the same is true for the V– supply pin. Referring to the Simplified Schematic, the LT6015/LT6016/ LT6017 has two input stages: a common emitter differential input stage consisting of PNP transistors Q1 and Q2 which operate when the inputs are biased between V– and 1.5V below V+, and a common base input stage consisting of PNP transistors Q3 to Q6 which operate when the common mode input is biased greater than V+ –1.5V. This results in two distinct operating regions as shown in Figure 2. The LT6017 consists of two dual amplifier dice assembled in a single DFN package which share a common substrate (V–). While the V– pins of the quad (pins 16 and 18) must always be tied together and to the exposed pad underneath, the V+ power supply pins (pins 5 and 7) may be supplied independently. The B and C channel amplifiers are supplied through V+ by pin 7, and the A and D channel amplifiers are supplied by pin 5. If pin 5 and pin 7 are not tied together and are biased independently, each V+ pin should have their own dedicated supply bypass to ground. For common mode input voltages approximately 1.5V or more below the V+ supply (Q1 and Q2 active), the common emitter PNP input stage is active and the input bias current is typically under ±2nA. When the common mode input is within approximately 1V of the V+ supply or higher –50V OK! + Shutdown While there are no dedicated shutdown pins for the LT6015/ LT6016/LT6017, the amplifiers can effectively be shut down into a low power state by removing V+. In this condition the input bias current is typically less than 1nA with the inputs biased between V– and 76V above V–, and if the inputs are taken below V–, they appear as a diode in series with 1k of resistance. The output may be pulled up to 50V above the V+ power supply in this condition (See Figure 1). Pulling the output pin below V– will produce unlimited current and can damage the part. + – – The LT6015/LT6016/LT6017 are protected against reverse battery voltages up to 50V. In the event a reverse battery condition occurs, the supply current is typically less than 5µA (assuming the inputs are biased within a diode drop from V–). For typical single supply applications with ground referred loads and feedback networks, no other precautions are required. If the reverse battery condition results in a negative voltage at the input pins, the current into the pin should be limited by an external resistor to less than 10mA. + 80V REVERSE BATTERY TOLERANT 5V OK! 80V INPUTS DRIVEN ABOVE SUPPLY TOLERANT + 5V OK! + + – – 25V TRANSIENT LARGE DIFFERENTIAL INPUT VOLTAGE TOLERANT Reverse Battery 5V OK! + INPUTS DRIVEN BELOW GROUND TOLERANT 0V OK! – + – 50V + 601567 F01 OUTPUT DRIVEN ABOVE THE V+ SUPPLY (IN SHUTDOWN) TOLERANT Figure 1.

Adding additional external series resistance will extend the protection beyond 25V below V–. The input stage of the LT6015/LT6016/LT6017 incorporates phase reversal protection to prevent the output from phase reversing for inputs below V–. There are no clamping diodes between the inputs. The inputs may be over-driven differentially to 80V without damage, or without drawing appreciable input current. Figure 1 summarizes the kind of faults that may be applied to the LT6015/LT6016/LT6017 without damage. Over-The-Top Operation Considerations When the input common mode of the LT6015/LT6016/ LT6017 is biased near or above the V+ supply, the amplifier is said to be operating in the Over-The-Top configuration. The differential input pair which control amplifier operation is common base pair Q3 to Q6 (refer to the Simplified Schematic). If the input common mode is biased between V– and approximately 1.5V below V+, the amplifier is said to be operating in the normal configuration. The differential input pair which control amplifier operation is common emitter pair Q1 and Q2. A plot of the Over-The-Top Transition region vs Temperature (the region between normal operation and Over-The-Top operation) on a 5V single supply is shown in Figure 2. 14 5.0 4.5 VS = 5V 4.0 3.5 VCM (V) (Over-The-Top operation), Q9 begins to turn on diverting bias current away from the common emitter differential input pair to the current mirror consisting of Q11 and Q12. The current from Q12 will bias the common base differential input pair consisting of Q3 to Q6. Because the Over-The-Top input pair is operating in a common base configuration, the input bias current will increase to about 14μA. Both input stages have their voltage offsets trimmed tightly and are specified in the Electrical Characteristics table. TYPICAL COMMON MODE VOLTAGE FOR ONSET OF OVER-THE-TOP OPERATION 3.0 2.5 2.0 TYPICAL COMMON MODE VOLTAGE WHERE OVER-THE-TOP OPERATION FULLY ON 1.5 1.0 TRANSISTION REGION 0.5 0 –50 –25 0 25 75 50 TEMPERATURE (°C) 100 125 150 601567 F02 Figure 2. LT6016/LT6017 Over-The-Top Transition Region vs Temperature Some implications should be understood about OverThe-Top operation. The first, and most obvious is the input bias currents change from under ±2nA in normal operation to 14µA in Over-The-Top operation as the input stage transitions from common emitter to common base. Even though the Over-The-Top input bias currents run around 14 µA, they are very well matched and their offset is typically under ±100nA. The second and more subtle change to amplifier operation is the differential input impedance which decreases from 1MΩ in normal operation, to approximately 3.7kΩ in Over-The-Top operation (specified as RIN in the Electrical Characteristics table). This resistance appears across the summing nodes in Over-The-Top operation and is due to the common base input stage configuration. Its value is easily derived from the specified input bias current flowing into the op amp inputs and is equal to 2 • k • T/(q • Ib) (k-Boltzmann’s constant, T – operating temperature, Ib-operating input bias current of the amplifier in the Over-The-Top region). And because the inputs are biased proportional to absolute temperature, it is relatively constant with temperature. The user may think this effective resistance is relatively harmless because it appears across the summing nodes which are forced 601567ff For more information www.linear.com/LT6015 LT6015/LT6016/LT6017 Applications Information to 0V differential by feedback action of the amplifier. However, depending on the configuration of the feedback around the amplifier, this input resistance can boost noise gain, lower overall amplifier loop gain and closed loop bandwidth, raise output noise, with one benevolent effect in increasing amplifier stability. In the normal mode of operation (where V– < VCM < V+ –1.5V), RIN is typically large compared to the value of the input resistor used, and RIN can be ignored (refer to Figure 3). In this case the noise gain is defined by the equation: R NOISE GAIN ≈ 1+ F RI However, when the amplifier transitions into Over-The-Top mode with the input common mode biased near or above the the V+ supply, RIN should be considered. The noise gain of the amplifier changes to: NOISE GAIN = 1+ RF RI || (RIN + RI || R F ) VIN VINCM RI 5V + RIN LT6015 Normal mode: BWCLOSED − LOOP ≈ GBW R 1+ F RI Over-The-Top mode: BWCLOSED − LOOP ≈ GBW RF 1+ RI || (RIN + RI || R F ) And output noise is negatively impacted going from normal mode to Over-The-Top: Normal mode: (neglecting resistor noise) ⎛ R ⎞ eno ≈ eni • ⎜ 1+ F ⎟ ⎝ RI ⎠ Over-The-Top mode: (neglecting resistor noise) RF RI Likewise the closed loop bandwidth of the amplifier will change going from normal mode operation to Over-TheTop operation: VOUT – ⎛ ⎞ RF eno ≈ eni • ⎜ 1+ ⎟ ⎝ RI || (RIN + RI || R F ) ⎠ Output RF 601567 F03 Figure 3.

The output is capable of sourcing and sinking approximately 25mA. The LT6015/LT6016/LT6017 are internally compensated to drive at least 200pF of capacitance under any output loading conditions. For larger capacitive loads, a 0.22μF capacitor in series with a 150Ω resistor between the output and ground will compensate these amplifiers to drive capacitive loads greater than 200pF. 601567ff For more information www.linear.com/LT6015 15 LT6015/LT6016/LT6017 Applications Information 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. If the op amp is operating in an inverting configuration there is no common mode induced distortion. If the op amp is operating in the noninverting configuration within the normal input common mode range (V– to V+ –1.5V) the CMRR is very good, typically over 120dB. When the LT6015/LT6016/ LT6017 transitions input stages going from the normal input stage to the Over-The-Top input stage or vice-versa, there will be a significant degradation in linearity due to the change in input circuitry. Lower load resistance increases distortion due to a net decrease in loop gain, and greater voltage swings internal to the amp necessary to drive the load, but has no effect on the input stage transition distortion. The lowest distortion can be achieved with the LT6015/LT6016/LT6017 sourcing in class-A operation in an inverting configuration, with the input common mode biased mid-way between the supplies. Power Dissipation Considerations Because of the ability of the LT6015/LT6016/LT6017 to operate on power supplies up to ±25V and to drive heavy loads, there is a need to ensure the die junction temperature does not exceed 150°C. The LT6015 is housed in a 5-lead TSOT-23 package (JA = 250°C/W). The LT6016 is housed in an 8-lead MSOP package (JA = 273°C/W). The LT6017 is housed in a 22 pin leadless DFN package (DJC22, JA = 31.8°C/W). 16 In general, the die junction temperature (TJ) can be estimated from the ambient temperature TA, and the device power dissipation PD: TJ = TA + PD • JA The power dissipation in the IC is a function of supply voltage and load resistance. For a given supply voltage, the worst-case power dissipation PD(MAX) occurs at the maximum supply current with the output voltage at half of either supply voltage (or the maximum swing is less than one-half the supply voltage). PD(MAX) is given by: PD(MAX) = (VS • IS(MAX)) + (VS/2)2/RLOAD Example: An LT6016 in a MSOP package mounted on a PC board has a thermal resistance of 273°C/W. Operating on ±25V supplies with both amplifiers simultaneously driving 2.5kΩ loads, the worst-case IC power dissipation for the given load occurs when driving 12.5VPEAK and is given by: PD(MAX) = 2 • 50 • 0.6mA + 2 • (12.5)2/2500 = 0.185W With a thermal resistance of 273°C/W, the die temperature will experience approximately a 50°C rise above ambient. This implies the maximum ambient temperate the LT6016 should ever operate under the assumed conditions: TA = 150°C – 50°C = 100°C To operate to higher ambient temperatures, use two channels of the LT6017 quad which has lower thermal resistance JA = 31.8°C/W, and an exposed pad which may be soldered down to a copper plane (connected to V–) to further lower the thermal resistance below JA = 31.8°C/W. 601567ff For more information www.linear.com/LT6015 LT6015/LT6016/LT6017 Simplified Schematic V+ Q10 PNP R5 40k I1 I3 I4 16µA 8µA 8µA M2 PMOS R1, 1k Q9 PNP –IN I2 5µA R2, 1k +IN Q3 PNP Q6 PNP Q11 NPN Q4 PNP P CLASS AB ADJUST N Q1 PNP Q2 PNP Q5 PNP Q12 NPN D3 Q7 NPN D1 OUT Q8 NPN R3 6k D2 M1 PMOS R4 6k V– Q13 NPN D4 601567 SS Typical Applications Gain of 100 High Voltage Difference Amplifier with –5V/75V Common Mode Range CMRR ADJUST 97.6k 1k + VIN VCM 1k – + 5V 5k + VOUT = 100 • VIN LT6015 – –5V – 100k 601567 TA02 Wide Input Range Current Sense Amp Goes Hi-Z When VSUPPLY Removed VSUPPLY 0.1µF VSOURCE = 0.2V TO 76V R1 200Ω ISENSE 0.1Ω RSENSE R2 200Ω + LT6016 – LOAD R6 100Ω 1% BSP89 R3 200Ω + LT6016 – VSUPPLY = 3V TO 60V R4 200Ω *DIODE IMPROVES OUTPUT SWING LOW R5 10k 1N4148* VOUT ⎛ R5 ⎞ VOUT = RSENSE • ISENSE ⎜ 1+ ⎟ ⎝ R4 ⎠ 601567 TA04 601567ff For more information www.linear.com/LT6015 17 LT6015/LT6016/LT6017 Package Description Please refer to http://www.linear.com/designtools/packaging/ for the most recent package drawings.
