What this dual CMOS op-amp is for
The Texas Instruments TLC27L2IPWR is a dual CMOS operational amplifier from the LinCMOS™ family, packing two low-power amplifiers into an 8-TSSOP surface-mount package. It draws just 20 µA per channel, making it a natural fit for battery-powered instrumentation, portable medical sensors, and remote data-acquisition nodes where every microamp of supply current is budgeted. The 110 kHz gain-bandwidth product and 0.03 V/µs slew rate tell you this part is for slow, precision signals — think thermocouple amplifiers, photodiode front-ends, or micropower filters — not audio or motor-control loops.
Input bias current — the photodiode and high-Z signal play
The 0.6 pA typical input bias current is exceptionally low, a direct benefit of the CMOS input stage. For a photodiode amplifier or a pH probe buffer, that bias current won't swamp the signal — you can use feedback resistors in the tens of megohms without the offset error climbing into the millivolt range. The 1.1 mV input offset voltage is typical for a CMOS part at this price point; if your application needs sub-millivolt precision, you'll want to null it or select a trimmed variant.
Supply range and temperature grade
Runs on a single supply from 4 V to 16 V, or split supplies up to ±8 V. The -40°C to 85°C operating range covers industrial and outdoor telecom cabinets — not automotive under-hood, but fine for factory-floor sensor modules and HVAC controllers. The 8-TSSOP package (0.173" body width) is a compact footprint; verify your PCB land pattern matches the 4.40 mm width before layout.
Lifecycle and sourcing
TI lists the TLC27L2IPWR as Active with ROHS3 compliance. No last-time-buy notice, no NRND flag — it's a current-production part. Sourced through independent distribution and quoted to order against an RFQ.
