3 Description
The OPA172, OPA2172 and OPA4172 (OPAx172)
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). This latest addition of high-voltage CMOS
operational amplifiers, in conjunction with the
OPAx171 and OPAx170, provide a family of
bandwidth, noise, and power options to meet the
needs of a wide variety of applications. The OPAx172
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, which are specified at only one
supply voltage, the OPAx172 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 series of op amps are specified from
–40°C to +125°C.
