FEATURES
DESCRIPTION
● MICRO-SIZE, TSSOP PACKAGE
● SINGLE-SUPPLY OPERATION
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.
● WIDE SUPPLY RANGE: 2.2V to 36V
● LOW QUIESCENT CURRENT: 45µA/chan
● WIDE BANDWIDTH: 430kHz
● WIDE INPUT/OUTPUT SWING
APPLICATIONS
● LCD DISPLAY DRIVERS
● BATTERY POWERED SYSTEMS
● PORTABLE EQUIPMENT
● PCMCIA CARDS
● BATTERY PACKS AND POWER SUPPLIES
● CONSUMER PRODUCTS
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.

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.
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.

APPLICATION INFORMATION
PRINTED CIRCUIT BOARD LAYOUT
See Burr-Brown Application Note AB-132 for specific PC
board layout recommendations.
The OPA4243 is unity-gain stable and suitable for a wide
range of general-purpose applications. The power supply
pins should be bypassed with 0.01µF ceramic capacitors.
INPUT PROTECTION
Rail-to-rail input signals will not cause damage or invert the
output of the OPA4243. To protect against ESD and excessive input voltage (beyond the supply rails) the OPA4243
includes diodes from the input terminals to the power supply
rails. Normally, these diodes are reversed biased and have
negligible effect on circuit operation. However, if the input
voltage is allowed to exceed the supply voltages by enough
to forward bias these diodes (generally, 0.3V to 0.6V)
excessive input current could flow. If this condition could
occur (for example, if an input signal is applied when the op
amp supply voltage is zero), care should be taken to limit the
input current to less than 10mA to avoid damage. An input
signal beyond the supplies, with power applied, can cause an
unexpected output inversion.
OPERATING VOLTAGE
The OPA4243 can operate from single supply (2.2V to 36V)
or dual supplies (±1.1V to ±18V) with excellent performance. Unlike most op amps which are specified at only one
supply voltage, the OPA4243 is specified for real world
applications; a single set of specifications applies throughout the 2.6V to 36V supply range. This allows the designer
to have the same assured performance at any supply voltage
within this range.
In addition, many key parameters are guaranteed over the
specified temperature range, –40°C to +85°C. Most behaviors remain unchanged throughout the full operating voltage
range. Parameters, which vary significantly with operating
voltage or temperature, are shown in the typical performance curves.
