Texas Instruments TLVx172/TLVx172-Q1 Rail-to-Rail Output Op Amps
Texas Instruments TLVx172/TLVx172-Q1 Rail-to-Rail Output Operational Amplifiers are electromagnetic interference (EMI) hardened, 36V, single-supply, low-noise operational amplifiers (op amps). These op amps feature a THD+N of 0.0002% at 1kHz with the ability to operate on supplies ranging from 4.5V (±2.25V) to 36V (±18V). These features, along with low noise and very high PSRR, make the TLVx172 an excellent choice for microvolt-level signal amplification. The TLVx172/TLVx172-Q1 offers good offset and drift, high bandwidth of 10MHz, and a slew rate of 10V/µs with only 2.3mA (max) of quiescent current over temperature.
Unlike most operational amplifiers specified at only one supply voltage, the TLVx172 is specified from 4.5V to 36V. Input signals beyond the supply rails do not cause phase reversal. These op amps are 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. The Texas Instruments TLVx172-Q1 devices are AEC-Q100 qualified for automotive applications.
