The 36-V TLVx171 family provides a low-power option for cost-conscious industrial and personal electronics systems requiring an electromagnetic interference (EMI)-hardened, low-noise, single-supply operational amplifier (op amp) that operates on supplies ranging from 2.7 V (±1.35 V) to 36 V (±18 V). The single-channel TLV171, dual-channel TLV2171, and quad-channel TLV4171 provide low offset, drift, quiescent current balanced with high bandwidth for the power. The devices are available in micropackages for space-constrained systems and feature identical specifications for maximum design flexibility.

Unlike most op amp, which are specified at only one supply voltage, the TLVx171 family is specified from 2.7 V to 36 V. Input signals beyond the supply rails do not cause phase reversal. The TLVx171 family is stable with capacitive loads up to 200 pF. The input can operate 100 mV below the negative rail and within 2 V of the top rail during normal operation. These devices can operate with a full rail-to-rail input 100 mV beyond the top rail, but with reduced performance within 2 V of the top rail.

The TLVx171 op amp family is specified from –40°C to +125°C.
