The standout spec is the input bias current: 0.7 pA typical, which means you can interface directly with high-impedance sources like photodiodes or pH probes without adding a separate buffer stage. Supply current sits at 950 µA — not the lowest in class, but reasonable for a part that runs from a single 3 V to 16 V rail or split supplies.
The TLC271CPWR operates from a single supply spanning 3 V to 16 V, or split supplies up to ±8 V. The output can source or sink 30 mA, enough to drive an ADC input or a small load directly.
