100 kHz CMOS op-amp for low-frequency sensor conditioning
The STMicroelectronics TS27L2IDT is a dual-channel CMOS operational amplifier with a gain-bandwidth product of 100 kHz, making it suitable for conditioning signals from slow sensors like thermocouples, strain gauges, or photodiodes where the signal bandwidth stays well below the audio range. Each amplifier draws 10 µA of supply current, so the dual package consumes 20 µA total quiescent — this is the defining spec for battery-powered or energy-harvesting designs where every microamp counts.
The input offset voltage is 1.1 mV typical — for a 10 mV full-scale sensor signal this represents an 11% offset error that must be calibrated out in software or trimmed with a reference voltage at the non-inverting input.
Package and lifecycle for BOM planning
The part is ROHS3 compliant, so it meets the current restriction on hazardous substances for European and global markets.
