DESCRIPTION

The OPA4243 is a four-channel op amp specifically

designed for high density, space-limited applications,

such as LCD bias drivers, PCMCIA cards, batterypacks

and portable instruments. In addition to small

size, this part features wide output swing, very low

quiescent current, and low bias current. Other features

include unity gain stability and the best speed power

ratio available. Power supplies in the range of 2.2V to

36V (±1.1V to ±18V) can be used.

Each channel uses completely independent circuitry

for lowest crosstalk and freedom from interaction,

even when overloaded. In addition, the amplifier is

free from output inversion when the inputs are driven

to the rail. The OPA4243EA is supplied in the miniature

TSSOP-14 surface mount package. Specifications

apply from –40°C to +85°C. However, as the extensive

typical performance curves indicate, the OPA4243

can be used over the full –55°C to +125°C range. A

SPICE macromodel is available for design analysis.
