The OPA4243 is a four-channel op amp specifically
designed for high density, space-limited applications,
such as LCD bias drivers, PCMCIA cards, battery-
packs 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 minia-
ture TSSOP-14 surface mount package. Specifications
apply from –40°C to +85°C. However, as the exten-
sive 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.
