Quad op-amp with rail-to-rail output swing
The TLV4171IPWR packages four general-purpose op-amp channels in a 14-TSSOP footprint, each capable of swinging its output to within millivolts of either supply rail. Each amplifier draws 525 µA of supply current, so the quad package consumes about 2.1 mA total. On a 24 V industrial loop-powered sensor, that quiescent draw sits well below the 4 mA loop floor, leaving the full 3.5 mA signal span for the transducer.
At a closed-loop gain of 10, the -3 dB bandwidth drops to roughly 300 kHz — enough margin for a 100 kHz PWM feedback filter. Input offset voltage is trimmed to 750 µV max, and input bias current is 10 pA typical. For a high-impedance source like a pH probe or a photodiode with a 10 MΩ shunt resistor, the 10 pA bias creates a 100 µV drop across the source — negligible compared to the offset spec.
The TLV4171IPWR operates from a single-supply span of 2.7 V to 36 V.
