FEATURES
● MICRO-SIZE, TSSOP PACKAGE

● WIDE SUPPLY RANGE: 2.2V to 36V
● LOW QUIESCENT CURRENT: 45µA/chan
● WIDE BANDWIDTH: 430kHz
● WIDE INPUT/OUTPUT SWING
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.

NOTES: (1) Stresses above these ratings may cause permanent damage.
Exposure to absolute maximum conditions for extended periods may degrade
device reliability. (2) Inputs are diode-clamped to the supply rails and should
be current-limited to 10mA or less if input voltages can exceed rails by more
than 0.3V. (3) Short-circuit to ground, one amplifier per package.

ELECTROSTATIC
DISCHARGE SENSITIVITY
This integrated circuit can be damaged by ESD. Burr-Brown
recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling
and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits
may be more susceptible to damage because very small
parametric changes could cause the device not to meet its
published specifications.
