Texas Instruments OPAx172/OPAx172-Q1 Rail-to-Rail Op Amps

Texas Instruments OPAx172/OPAx172-Q1 Rail-to-Rail Operational Amplifiers are 36V, single-supply, low-noise operational amplifiers. Each is capable of operating on supplies ranging from +4.5V (±2.25V) to +36V (±18V). These high-voltage CMOS operational amplifiers provide bandwidth, noise, and power options to meet the needs of a wide variety of applications. The OPAx172/OPAx172-Q1 are available in micro packages 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 (OPA172), dual (OPA2172), and quad (OPA4172) versions all have identical specifications for maximum design flexibility. Texas Instruments OPAx172-Q1 devices are AEC-Q100 qualified for automotive applications.
