DESCRIPTION
The OPA170, OPA2170 and OPA4170 (OPAx170)
are a family of 36V, single-supply, low-noise
operational amplifiers that feature micro packages
with the ability to operate on supplies ranging from
+2.7V (±1.35V) to +36V (±18V). They offer good
offset, drift, and bandwidth with low quiescent current.
The single, dual, and quad versions all have identical
specifications for maximum design flexibility.
Unlike most op amps, which are specified at only one
supply voltage, the OPAx170 family of op amps is
specified from +2.7V to +36V. Input signals beyond
the supply rails do not cause phase reversal. The
OPAx170 family is stable with capacitive loads up to
300pF. The input can operate 100mV below the
negative rail and within 2V of the positive rail for
normal operation. Note that these devices can
operate with full rail-to-rail input 100mV beyond the
positive rail, but with reduced performance within 2V
of the positive rail.
The OPA170 is available in SOT553, SOT23-5, and
SO-8 packages. The dual OPA2170 comes in
VSSOP-8, MSOP-8, and SO-8 packages. The quad
OPA4170 is offered in TSSOP-14 and SO-14
packages. The OPAx170 op amps are specified
from –40°C to +125°C.
