OPA2170AIDR

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.
