Texas Instruments TLVx172/TLVx172-Q1轨到轨输出运算放大器
Texas Instruments TLVx172/TLVx172-Q1轨到轨输出运算放大器是36V、单电源、低噪声的抗电磁干扰 (EMI) 运算放大器。这些运算放大器在1kHz时具有0.0002%的THD+N，能够在4.5V (±2.25V) 至36V (±18V) 的电压范围内工作。除了以上特性外，TLVx172还具有低噪声和极高的PSRR，因此非常适合用于微伏级信号放大应用。TLVx172/TLVx172-Q1具有良好的失调和漂移、10MHz的高带宽、10V/µs的转换率，并且在过热条件下仅消耗2.3mA（最大值）的静态电流。与大部分被指定为仅可用于一种电源电压的运算放大器不同，TLVx172适用于4.5V至36V的电压范围。超出电源轨的输入信号不会导致反相。这些运算放大器在电容负载高达 300pF 的情况下仍可保持稳定。输入可在负电源轨以下100mV以及正电源轨2V之内正常运行。TLVx172-Q1器件符合汽车应用类AEC-Q100认证。
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.
