LMC7111 Tiny CMOS Operational Amplifier with Rail-to-Rail Input and Output General Description The LMC7111 is a micropower CMOS operational amplifier available in the space saving SOT 23-5 package. This makes the LMC7111 ideal for space and weight critical designs. The wide common-mode input range makes it easy to design battery monitoring circuits which sense signals above the V+ supply. The main benefits of the Tiny package are most apparent in small portable electronic devices, such as mobile phones, pagers, and portable computers. The tiny amplifiers can be placed on a board where they are needed, simplifying board layout.

Because they are easier to carry, many customers prefer smaller and lighter products. 01235214 FIGURE 1. RI Input Current Protection for Voltages Exceeding the Supply Voltage Height 3.0 CAPACITIVE LOAD TOLERANCE The height (0.056 inches, 1.43 mm) of the Tiny amp makes it possible to use it in PCMCIA type III cards. The LMC7111 can typically directly drive a 300 pF load with VS = 10V at unity gain without oscillating. The unity gain follower is the most sensitive configuration. Direct capacitive loading reduces the phase margin of op-amps. The combination of the op-amp’s output impedance and the capacitive load induces phase lag. This results in either an underdamped pulse response or oscillation. Signal Integrity Signals can pick up noise between the signal source and the amplifier. By using a physically smaller amplifier package, the Tiny amp can be placed closer to the signal source, reducing noise pickup and increasing signal integrity. The Tiny amp can also be placed next to the signal destination, such as a buffer for the reference of an analog to digital converter. Capacitive load compensation can be accomplished using resistive isolation as shown in Figure 2. This simple technique is useful for isolating the capacitive input of multiplexers and A/D converters. Simplified Board Layout The Tiny amp can simplify board layout in several ways. First, by placing an amp where amps are needed, instead of routing signals to a dual or quad device, long pc traces may be avoided. By using multiple Tiny amps instead of duals or quads, complex signal routing and possibly crosstalk can be reduced. 01235212 DIPs available for prototyping LMC7111 amplifiers packaged in conventional 8-pin dip packages can be used for prototyping and evaluation without the need to use surface mounting in early project stages. FIGURE 2. Resistive Isolation of a 330 pF Capacitive Load 4.0 COMPENSATING FOR INPUT CAPACITANCE WHEN USING LARGE VALUE FEEDBACK RESISTORS When using very large value feedback resistors, (usually > 500 kΩ) the large feed back resistance can react with the input capacitance due to transducers, photodiodes, and circuit board parasitics to reduce phase margins. The effect of input capacitance can be compensated for by adding a feedback capacitor. The feedback capacitor (as in Figure 3), Cf is first estimated by: Low Supply Current The typical 25 µA supply current of the LMC7111 extends battery life in portable applications, and may allow the reduction of the size of batteries in some applications. Wide Voltage Range The LMC7111 is characterized at 2.7V, 3V, 3.3V, 5V and 10V. Performance data is provided at these popular voltages. This wide voltage range makes the LMC7111 a good choice for devices where the voltage may vary over the life of the batteries. 2.0 INPUT COMMON MODE VOLTAGE RANGE The LMC7111 does not exhibit phase inversion when an input voltage exceeds the negative supply voltage. The absolute maximum input voltage is 300 mV beyond either rail at room temperature. Voltages greatly exceeding this maximum rating can cause excessive current to flow in or out of the input pins, adversely affecting reliability. Applications that exceed this rating must externally limit the maximum input current to ± 5 mA with an input resistor as shown in Figure 1. or R1 CIN ≤ R2 Cf which typically provides significant overcompensation. Printed circuit board stray capacitance may be larger or smaller than that of a breadboard, so the actual optimum value for CF may be different. The values of CF should be checked on the actual circuit. (Refer to the LMC660 quad CMOS amplifier data sheet for a more detailed discussion.) 15 www.national.com LMC7111 Application Information (Continued) 5.0 OUTPUT SWING The output of the LMC7111 will go to within 100 mV of either power supply rail for a 10 kΩ load and to 20 mV of the rail for a 100 kΩ load. This makes the LMC7111 useful for driving transistors which are connected to the same power supply. By going very close to the supply, the LMC7111 can turn the transistors all the way on or all the way off. 6.0 BIASING GaAs RF AMPLIFIERS The capacitive load capability, low current draw, and small size of the SOT23-5 LMC7111 make it a good choice for providing a stable negative bias to other integrated circuits. The very small size of the LMC7111 and the LM4040 reference take up very little board space. 01235213 FIGURE 3. Cancelling the Effect of Input Capacitance 01235217 CF and Risolation prevent oscillations when driving capacitive loads. FIGURE 4. Stable Negative Bias 7.0 REFERENCE BUFFER FOR A-TO-D CONVERTERS The small size of the LMC7111 allows it to be placed close to the reference input. The low supply current (25 µA typical) saves power. The LMC7111 can be used as a voltage reference buffer for analog-to-digital converters. This works best for A-to-D converters whose reference input is a static load, such as dual slope integrating A-to-Ds. Converters whose reference input is a dynamic load (the reference current changes with time) may need a faster device, such as the LMC7101 or the LMC7131. For A-to-D reference inputs which require higher accuracy and lower offset voltage, please see the LMC6462 datasheet. The LMC6462 has performance similar to the LMC7111. The LMC6462 is available in two grades with reduced input voltage offset. 01235218 www.national.com 16 include — LMC7101 1 MHz gain-bandwidth rail-to-rail input and output amplifier — high input impedance and high gain, 700 µA typical current 2.7V, 3V, 5V and 15V specifications.
