OPA4170AQPWRQ1

The OPA170-Q1, OPA2170-Q1, and OPA4170-Q1 devices (OPAx170-Q1) are a family of 36V, single-supply, low-noise op amps. This device family is available in miniature packages and operates from supplies ranging from 2.7V (±1.35V) to 36V (±18V). These devices provide excellent offset, drift, and bandwidth while maintaining low quiescent current. Unlike most op amps that are specified at only a single supply voltage, the OPAx170-Q1 family is rated for operation across the full 2.7V to 36V range. Input signals beyond the supply rails do not cause phase reversal. The OPAx170-Q1 family remains stable with capacitive loads up to 300pF. The inputs operate properly from 100mV below the negative supply rail to within 2V of the positive supply rail. Note that these devices can operate with true rail-to-rail input 100mV above the positive supply rail, but performance is degraded when operating within 2V of the positive supply rail. The OPAx170-Q1 op amps are rated for operation over the temperature range of -40°C to +125°C.
