Application Information

1.0 Benefits of the LMC7111

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 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.

DIPs available for prototyping. LMC7111 amplifiers pack-

aged in conventional 8-pin dip packages can be used for

prototyping and evaluation without the need to use surface

mounting in early project stages.
