The OPA2172-Q1 and OPA4172-Q1 (OPAx172-Q1) are a
family of 36-V, single-supply, low-noise operational amplifiers capable of operating on supplies
ranging from 4.5 V (±2.25 V) to 36 V
(±18 V). The OPAx172-Q1 are available in micropackages, and offer low offset, drift, and
quiescent current. These devices also offer wide bandwidth, fast slew rate, and high output current
drive capability. The dual and quad versions all have identical specifications for maximum design
Unlike most op amps that are specified at only one supply voltage, the OPAx172-Q1 family
is specified from 4.5 V to 36 V. Input signals beyond the supply rails do not cause phase reversal.
The input can operate 100 mV below the negative rail and within 2 V of the top rail during normal
operation. Note that these devices can operate with full rail-to-rail input 100 mV beyond the top
rail, but with reduced performance within 2 V of the top rail.
The OPAx172-Q1 series of op amps are specified from –40°C to +125°C.
