The LT1214 is a quad version of the same amplifier. The DC precision of the LT1213/LT1214 eliminates trims in most systems while providing high frequency performance not usually found in single supply amplifiers. The LT1213/LT1214 will operate on any supply greater than 2.5V and less than 36V total. These amplifiers are specified at single 3.3V, single 5V and ±15V supplies, and only require 2.7mA of quiescent supply current per amplifier. The inputs can be driven beyond the supplies without damage or phase reversal of the output. The minimum output drive is 30mA, ideal for driving low impedance loads.

Note 2: A heat sink may be required to keep the junction temperature below absolute maximum when the output is shorted indefinitely. Note 3: TJ is calculated from the ambient temperature TA and power dissipation PD according to the following formulas: LT1213MJ8, LT1213AMJ8: TJ = TA + (PD × 100°C/W) LT1213CN8, LT1213ACN8: TJ = TA + (PD × 100°C/W) LT1213CS8: TJ = TA + (PD × 150°C/W) LT1214CN: TJ = TA + (PD × 70°C/W) LT1214CS: TJ = TA + (PD × 100°C/W) Note 4: This parameter is not 100% tested. Note 5: Guaranteed by correlation to 3.3V and ±15V tests. Note 6: The LT1213/LT1214 are designed, characterized and expected to meet these extended temperature limits, but are not tested at –40°C and 85°C. Guaranteed I grade parts are available.

The amplifiers will continue to function with as little as 1.5V, although the input common mode range and the phase margin are about gone. The minimum operating supply voltage is guaranteed by the PSRR tests which are done with the input common mode equal to 500mV and a minimum supply voltage of 2.5V. The LT1213/LT1214 are guaranteed over the full – 55°C to 125°C range with a minimum supply voltage of 2.5V. The positive supply pin of the LT1213/LT1214 should be bypassed with a small capacitor (about 0.01µF) within an inch of the pin. When driving heavy loads and for good settling time, an additional 4.7µF capacitor should be used. When using split supplies, the same is true for the negative supply pin. Power Dissipation The LT1213/LT1214 amplifiers combine high speed and large output current drive into very small packages. Because these amplifiers work over a very wide supply range, it is possible to exceed the maximum junction temperature under certain conditions. To insure that the LT1213/ LT1214 are used properly, calculate the worst case power dissipation, define the maximum ambient temperature, select the appropriate package and then calculate the maximum junction temperature. The worst case amplifier power dissipation is the total of the quiescent current times the total power supply voltage plus the power in the IC due to the load. The quiescent supply current of the LT1213/LT1214 has a positive temperature coefficient. The maximum supply current of each amplifier at 125°C is given by the following formula: ISMAX = 4.2 + 0.048 × (VS – 5) in mA VS is the total supply voltage. The power in the IC due to the load is a function of the output voltage, the supply voltage and load resistance. The worst case occurs when the output voltage is at half supply, if it can go that far, or its maximum value if it cannot reach half supply. U For example, calculate the worst case power dissipation while operating on ±15V supplies and driving a 500Ω load. ISMAX = 4.2 + 0.048 × (30 – 5) = 5.4mA PDMAX = 2 × VS × ISMAX + (VS – VOMAX) × VOMAX/RL PDMAX = 2 × 15V × 5.4mA + (15V – 7.5V) × 7.5V/500 = 0.162 + 0.113 = 0.275 Watt per Amp If this is the dual LT1213, the total power in the package is twice that, or 0.550W. Now calculate how much the die temperature will rise above the ambient. The total power dissipation times the thermal resistance of the package gives the amount of temperature rise. For this example, in the SO-8 surface mount package, the thermal resistance is 150°C/W junction-to-ambient in still air. Temperature Rise = PDMAX × θJA = 0.550W × 150°C/W = 82.5°C The maximum junction temperature allowed in the plastic package is 150°C. Therefore the maximum ambient allowed is the maximum junction temperature less the temperature rise. Maximum Ambient = 150°C – 82.5°C = 67.5°C That means the SO-8 dual can be operated at or below 67.5°C on ±15V supplies with a 500Ω load. As a guideline to help in the selection of the LT1213/ LT1214, the following table describes the maximum supply voltage that can be used with each part based on the following assumptions: 1. The maximum ambient is 70°C or 125°C depending on the part rating. 2. The load is 500Ω including the feedback resistors. 3. The output can be anywhere between the supplies.

However, the input bias current and offset voltage will shift as shown in the characteristic curves. For full precision performance, the common mode range should be limited between ground (V –) and 1.5V below the positive supply. When either of the inputs is taken below ground (V –) by more than about 700mV, that input current will increase dramatically. The current is limited by internal 100Ω resistors between the input pins and diodes to each supply. The output will remain low (no phase reversal) for inputs 1.3V below ground (V –). If the output does not have to sink current, such as in a single supply system with a 1k load to ground, there is no phase reversal for inputs up to 8V below ground. There are no clamps across the inputs of the LT1213/ LT1214 and therefore each input can be forced to any voltage between the supplies. The input current will remain constant at about 100nA over most of this range. When an input gets closer than 1.5V to the positive supply, that input current will gradually decrease to zero until the input goes above the supply, then it will increase due to the previously mentioned diodes. If the inverting input is held more positive than the noninverting input by 200mV or more, while at the same time the noninverting input is within 300mV of ground (V –), then the supply current will increase by 2mA and the noninverting input current will increase to about 10µA. This should be kept in mind in comparator applications where the inverting input stays above ground (V –) and the noninverting input is at or near ground (V –). Output The output of the LT1213/LT1214 will swing to within 0.61V of the positive supply with no load. The open-loop output resistance, when the output is driven hard into the S I FOR ATIO 14 U positive rail, is about 100Ω as the output starts to source current; this resistance drops to about 20Ω as the current increases. Therefore when the output sources 1mA, the output will swing to within 0.7V of the positive supply. While sourcing 30mA, it is within 1.25V of the positive supply. The output of the LT1213/LT1214 will swing to within 4mV of the negative supply while sinking zero current. Thus, in a typical single supply application with the load going to ground, the output will go to within 4mV of ground. The open-loop output resistance when the output is driven hard into the negative rail is about 29Ω at low currents and reduces to about 23Ω at high currents. Therefore when the output sinks 1mA, the output is about 33mV above the negative supply and while sinking 30mA, it is about 690mV above it. The output of the LT1213/LT1214 has reverse-biased diodes to each supply. If the output is forced beyond either supply, unlimited currents will flow. If the current is transient and limited to several hundred mA, no damage will occur. Feedback Components Because the input currents of the LT1213/LT1214 are less than 200nA, it is possible to use high value feedback resistors to set the gain. However, care must be taken to insure that the pole that is formed by the feedback resistors and the input capacitance does not degrade the stability of the amplifier. For example, if a single supply, noninverting gain of two is set with two 10k resistors, the LT1213/LT1214 will probably oscillate. This is because the amplifier goes open-loop at 6MHz (6dB of gain) and has 45° of phase margin. The feedback resistors and the 10pF input capacitance generate a pole at 3MHz that introduces 63° of phase shift at 6MHz! The solution is simple, lower the values of the resistors or add a feedback capacitor of 10pF or more. W U UO LT1213/LT1214 APPLICATI S I FOR ATIO Comparator Applications Sometimes it is desirable to use an op amp as a comparator. When operating the LT1213/LT1214 on a single 3.3V or 5V supply, the output interfaces directly with most TTL and CMOS logic.
