3 Description
The OPA172-Q1, 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 single, dual, and quad versions
all have identical specifications for maximum design
flexibility.
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.
