3 Description
The OPA170-Q1, OPA2170-Q1, and OPA4170-Q1
devices (OPAx170-Q1) are a family of 36-V, single-
supply, low-noise operational amplifiers that feature
micro packages with the ability to operate on supplies
ranging from 2.7 V (±1.35 V) to 36 V (±18 V). 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 operational amplifiers, which are
specified at only one supply voltage, the OPAx170-
Q1 family of operational amplifiers is specified from
2.7 V to 36 V. Input signals beyond the supply rails
do not cause phase reversal. The OPAx170-Q1
family is stable with capacitive loads up to 300 pF.
The input can operate 100 mV below the negative rail
and within 2 V of the positive rail for normal
operation. Note that these devices can operate with
full rail-to-rail input 100 mV beyond the positive rail,
but with reduced performance within 2 V of the
positive rail. The OPAx170-Q1 operational amplifiers
are specified from –40°C to +125°C.
