LMC7101  
Tiny Low Power Operational Amplifier with Rail-To-Rail  
Input and Output  
General Description  
Features  
n Tiny SOT23-5 package saves spacetypical circuit  
layouts take half the space of SO-8 designs  
n Guaranteed specs at 2.7V, 3V, 5V, 15V supplies  
n Typical supply current 0.5 mA at 5V  
n Typical total harmonic distortion of 0.01% at 5V  
n 1.0 MHz gain-bandwidth  
The LMC7101 is a high performance CMOS operational  
amplifier available in the space saving SOT 23-5 Tiny pack-  
age. This makes the LMC7101 ideal for space and weight  
critical designs. The performance is similar to a single am-  
plifier of the LMC6482/6484 type, with rail-to-rail input and  
output, high open loop gain, low distortion, and low supply  
currents.  
n Similar to popular LMC6482/6484  
The main benefits of the Tiny package are most apparent in  
small portable electronic devices, such as mobile phones,  
pagers, notebook computers, personal digital assistants,  
and PCMCIA cards. The tiny amplifiers can be placed on a  
board where they are needed, simplifying board layout.  
n Rail-to-rail input and output  
Applications  
n Mobile communications  
n Notebooks and PDAs  
n Battery powered products  
n Sensor interface

Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is  
intended to be functional, but specific performance is not guaranteed. For guaranteed specifications and the test conditions, see the Electrical Characteristics.  
Note 2: Human Body Model is 1.5 kin series with 100 pF.  
Note 3: Applies to both single-supply and split-supply operation. Continuous short operation at elevated ambient temperature can result in exceeding the maximum  
allowed junction temperature at 150˚C.

1.0 BENEFITS OF THE LMC7101  
TINY AMP  
Size  
The small footprint of the SOT 23-5 packaged Tiny amp,  
(0.120 x 0.118 inches, 3.05 x 3.00 mm) saves space on  
printed circuit boards, and enable the design of smaller  
electronic products. Because they are easier to carry, many  
customers prefer smaller and lighter products.  
Height  
The height (0.056 inches, 1.43 mm) of the Tiny amp makes  
it possible to use it in PCMCIA type III cards.

LMC7101 Power Supply Voltages with  
No Output Phase Inversion  
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.  
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 re-  
duced.

Low THD  
The high open loop gain of the LMC7101 amp allows it to  
achieve very low audio distortiontypically 0.01% at 10 kHz  
with a 10 kload at 5V supplies. This makes the Tiny an  
excellent for audio, modems, and low frequency signal pro-  
cessing.

Exceeds the 3V Supply in Figure 3 Causing  
No Phase Inversion Due to RI  
Applications that exceed this rating must externally limit the  
maximum input current to 5 mA with an input resistor as  
shown in Figure 3.  
Low Supply Current  
The typical 0.5 mA supply current of the LMC7101 extends  
battery life in portable applications, and may allow the reduc-  
tion of the size of batteries in some applications.  
Wide Voltage Range  
The LMC7101 is characterized at 15V, 5V and 3V. Perfor-  
mance data is provided at these popular voltages. This wide  
voltage range makes the LMC7101 a good choice for de-  
vices where the voltage may vary over the life of the batter-  
ies.

3.0 RAIL-TO-RAIL OUTPUT  
The LMC7101 does not exhibit phase inversion when an  
input voltage exceeds the negative supply voltage. Figure 1  
shows an input voltage exceeding both supplies with no  
resulting phase inversion of the output.  
The approximate output resistance of the LMC7101 is 180Ω  
sourcing and 130sinking at VS = 3V and 110sourcing  
and 80sinking at VS = 5V. Using the calculated output  
resistance, maximum output voltage swing can be estimated  
as a function of load.  
The absolute maximum input voltage is 300 mV beyond  
either rail at room temperature. Voltages greatly exceeding  
this maximum rating, as in Figure 2, can cause excessive  
current to flow in or out of the input pins, adversely affecting  
reliability.

4.0 CAPACITIVE LOAD TOLERANCE  
5.0 COMPENSATING FOR INPUT CAPACITANCE WHEN  
USING LARGE VALUE FEEDBACK RESISTORS  
The LMC7101 can typically directly drive a 100 pF load with  
VS = 15V 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 combi-  
nation of the op-amp’s output impedance and the capacitive  
load induces phase lag. This results in either an under-  
damped pulse response or oscillation.  
When using very large value feedback resistors, (usually  
>
500 k) the large feed back resistance can react with the  
input capacitance due to transducers, photodiodes, and cir-  
cuit 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 5), Cf is first estimated by:  
Capacitive load compensation can be accomplished using  
resistive isolation as shown in Figure 4. This simple tech-  
nique is useful for isolating the capacitive input of multiplex-  
ers and A/D converters.  
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.)
