TLV4171IDR

The 36V TLVx171 series provides a low-power option for cost-sensitive industrial and personal electronics systems requiring a low-noise, single-channel power op-amp with EMI rejection, operating over a supply voltage range of 2.7V (±1.35V) to 36V (±18V). The single-channel TLV171, dual-channel TLV2171, and quad-channel TLV4171 deliver low offset, drift, and quiescent current while maintaining high bandwidth. The series is available in multiple compact packages suited for space-constrained systems, with identical specifications across all packages to maximize design flexibility. Unlike most op-amps rated for operation at a single supply voltage, the TLVx171 series is rated for operation from 2.7V to 36V. Input signals beyond the supply rails do not cause phase reversal. The TLVx171 series remains stable with capacitive loads up to 200pF. Input signals operate normally from 100mV below the negative supply rail to 2V above the positive supply rail. These devices support rail-to-rail input operation up to 100mV above the positive supply rail, though performance degrades when operating within ±2V of the positive supply rail. The TLVx171 op-amp series is rated for operation over a temperature range of -40°C to +125°C.
