The OPA277 series precision op amps replace the industry
standard OP-177. They offer improved noise, wider output
voltage swing, and are twice as fast with half the quiescent
current. Features include ultra low offset voltage and drift, low
bias current, high common-mode rejection, and high power
supply rejection. Single, dual, and quad versions have identical
specifications for maximum design flexibility.
OPA277 series op amps operate from
±2V
to
±18V
supplies
with excellent performance. Unlike most op amps which
are specified at only one supply voltage, the OPA277 series
is specified for real-world applications; a single limit ap-
plies over the
±5V
to
±15V
supply range. High performance
is maintained as the amplifiers swing to their specified limits.
Because the initial offset voltage (±20µV max) is so low, user
adjustment is usually not required. However, the single version
(OPA277) provides external trim pins for special applications.
OPA277 op amps are easy to use and free from phase inversion
and overload problems found in some other op amps. They are
stable in unity gain and provide excellent dynamic behavior
over a wide range of load conditions. Dual and quad versions
feature completely independent circuitry for lowest crosstalk
and freedom from interaction, even when overdriven or over-
loaded.
Single (OPA277) and dual (OPA2277) versions are available
in 8-pin DIP and SO-8 surface-mount packages. The quad
(OPA4277) comes in 14-pin DIP and SO-14 surface-mount
packages. All are fully specified from –40°C to +85°C and
operate from –55°C to +125°C.

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 degrada-
tion 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.
