Texas Instruments TLVx171/TLVx171-Q1 36V General Purpose Op Amps

Texas Instruments TLVx171/TLVx171-Q1 36V General Purpose Operational Amplifiers provide a low-power option for cost-conscious industrial and personal electronics systems. These devices are ideal where an EMI-hardened, low-noise, single-supply operational amplifier that operates on supplies ranging from 2.7V (±1.35V) to 36V (±18V) is required. The single-channel TLV171/TLV171-Q1, dual-channel TLV2171, and quad-channel TLV4171 provide low offset, drift, quiescent current balanced with high bandwidth for the power. These devices are available in micro packages for space-constrained systems and feature identical specifications for maximum design flexibility. Unlike most op amps, which are specified at only one supply voltage, the TLVx171/TLVx171-Q1 family is specified from 2.7V to 36V. The Texas Instruments TLVx171-Q1 devices are AEC-Q100 qualified for automotive applications.
