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 kΩ in 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. Note 4: The maximum power dissipation is a function of TJ(MAX), θJA and TA. The maximum allowable power dissipation at any ambient temperature is PD = (TJ(MAX) − TA)/θJA. All numbers apply for packages soldered directly into a PC board. Note 5: Typical Values represent the most likely parametric norm. Note 6: All limits are guaranteed by testing or statistical analysis. Note 8: V+ = 15V. Connected as a voltage follower with a 10V step input. Number specified is the slower of the positive and negative slew rates. RL = 100 kΩ connected to 7.5V. Amp excited with 1 kHz to produce VO = 10 VPP. Note 9: Do not short circuit output to V+ when V+ is greater than 12V or reliability will be adversely affected.

Application Information

1.0 BENEFITS OF THE LMC7101

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 print- ed 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. 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 avoid- ed. 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 allows it to achieve very low audio distortion—typically 0.01% at 10 kHz with a 10 k Ω load at 5V supplies. This makes the Tiny an excellent for audio, modems, and low frequency signal pro- cessing. 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 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 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 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. 1199108 FIGURE 1.
