Dual CMOS op-amp for precision signal conditioning
The TLC2262ID: It features rail-to-rail output swing, which maximises dynamic range in single-supply designs from 4.4 V to 16 V. Input bias current is just 1 pA, making it suitable for high-impedance sensor interfaces such as photodiode amplifiers, pH probes, and piezoelectric transducers where bias current errors would otherwise dominate. Each channel draws 425 µA supply current, keeping the total dual-channel quiescent draw under 1 mA — a fit for battery-powered or thermally constrained industrial control boards.
The 125°C upper limit also suits downhole instrumentation and engine-bay sensor conditioning where ambient temperatures exceed 105°C.
Output drive and supply range
Each channel can source or sink 50 mA, enough to drive moderate loads like a 100 Ω headphone or an ADC reference buffer directly. The 4.4 V minimum supply span means it works with 5 V ±10% rails and 3.3 V systems only if the rail is boosted above 4.4 V — a 5 V rail is the practical floor for this part. At 16 V maximum supply, it fits 12 V and 15 V industrial rails with headroom for transients. Input offset voltage is 300 µV typical, adequate for 12-bit signal chains where the offset error stays below 1 LSB at a 2.5 V reference.
Lifecycle and compliance
It is suitable for both new design-ins and sustaining production. The ROHS3 compliance covers all six original substances plus the four phthalates, satisfying EU and global regulatory requirements without a separate certificate hunt.
