APPLICATIONS INFORMATION
The OPA363 and OPA364 series op amps are rail-to-rail
operational amplifiers with excellent CMRR, low noise, low
offset, and wide bandwidth on supply voltages as low as
±
0.9V. The OPA363 features an additional pin for shutdown/
enable function. These families do not exhibit phase reversal
and are unity-gain stable. Specified over the industrial tem-
perature range of
–
40
°
C to +125
°
C, the OPA363 and OPA364
families offer precision performance for a wide range of
applications.
RAIL-TO-RAIL INPUT
The OPA363 and OPA364 feature excellent rail-to-rail opera-
tion, with supply voltages as low as
±
0.9V. The input com-
mon-mode voltage range of the OPA363 and OPA364 family
extends 100mV beyond supply rails. The unique input topol-
ogy of the OPA363 and OPA364 eliminates the input offset
transition region typical of most rail-to-rail complimentary
stage operational amplifiers, allowing the OPA363 and
OPA364 to provide superior common-mode performance
over the entire common-mode input range, as seen in Figure 1.
This feature prevents degradation of the differential linearity
error and THD when driving A/D converters. A simplified
schematic of the OPA363 and OPA364 is shown in Figure 2.
OPERATING VOLTAGE
The OPA363 and OPA364 series op amp parameters are fully
specified from +1.8V to +5.5V. Single 0.1
μ
F bypass capaci-
tors should be placed across supply pins and as close to the
part as possible. Supply voltages higher than 5.5V (absolute
maximum) may cause permanent damage to the amplifier.
Many specifications apply from

C to +125

C. Parameters
that vary significantly with operating voltages or temperature
are shown in the Typical Characteristics.
