Application Information

1.0 Benefits of the LMC7101

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 elec- tronic products. Because they are easier to carry, many cus- tomers 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. Signal Integrity.Signals can pick up noise between the sig- nal 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 de- vice, long pc traces may be avoided. By using multiple Tiny amps instead of duals or quads, com- plex signal routing and possibly crosstalk can be reduced. Low THD. The high open loop gain of the LMC7101 amp al- lows it to achieve very low audio distortion — typically 0.01% at 10 kHz with a 10 kΩ load at 5V supplies. This makes the Tiny an excellent for audio, modems, and low frequency sig- nal processing. Low Supply Current.The typical 0.5 mA supply current of the LMC7101 extends battery life in portable applications, and may allow the reduction of the size of batteries in some applications. Wide Voltage Range. The LMC7101 is characterized at 15V, 5V and 3V. Performance data is provided at these popular voltages. This wide voltage range makes the LMC7101 a good choice for devices where the voltage may vary over the life of the batteries.

2.0 Input Common Mode

The LMC7101 does not exhibit phase inversion when an in- put voltage exceeds the negative supply voltage.Figure 1 shows an input voltage exceeding both supplies with no re- sulting phase inversion of the output. The absolute maximum input voltage is 300 mV beyond ei- ther 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. Applications that exceed this rating must externally limit the maximum input current to ±5 mA with an input resistor as shown inFigure 3.

3.0 Rail-To-Rail Output

The approximate output resistance of the LMC7101 is 180Ω sourcing and 130Ω sinking at VS = 3V and 110Ω sourcing and 80Ω sinking at VS = 5V. Using the calculated output re- sistance, maximum output voltage swing can be estimated as a function of load.

4.0 Capacitive Load Tolerance

The LMC7101 can typically directly drive a 100 pF load with V S = 15V at unity gain without oscillating. The unity gain fol- lower is the most sensitive configuration. Direct capacitive loading reduces the phase margin of op-amps. The combi- DS011991-8 FIGURE 1. An Input Voltage Signal Exceeds the FIGURE 2. A ±7.5V Input Signal Greatly FIGURE 3.
