Dual CMOS op-amp in DIP-8 — micropower signal chain for through-hole boards
The TLC27L2CP is a dual CMOS operational amplifier from Texas Instruments' LinCMOS™ series, packaged in an 8-pin DIP (0.300" pitch) for through-hole assembly. It draws just 20 µA total supply current across both channels, making it a fit for battery-powered or energy-harvesting circuits where every microamp counts. With a gain-bandwidth product of 110 kHz and a slew rate of 0.03 V/µs, this part is sized for low-frequency signal conditioning — sensor amplification, thermocouple front-ends, or comparator duties — not for audio or high-speed loops. The 0.6 pA typical input bias current preserves accuracy from high-impedance sources like photodiodes or pH probes.
Supply rails, output drive, and temperature range
Operates from a single supply spanning 3 V to 16 V (or dual supplies ±1.5 V to ±8 V). The 1.1 mV typical input offset voltage and 30 mA per-channel output current give it enough headroom to drive ADC inputs or small relays through a logic-level buffer. Rated for the commercial temperature range of 0°C to 70°C, so it belongs in indoor equipment, benchtop instruments, or environmental chambers — not under-hood or outdoor enclosures without climate control.
Lifecycle and sourcing — active, no second-source on record
Texas Instruments lists the TLC27L2CP as Active and ROHS3 compliant. No end-of-life notice or successor order code is published. The part is sourced through authorized and independent distribution; availability and current pricing are confirmed at RFQ against your BOM quantity. The OPA4374AIPWT is a quad, surface-mount (TSSOP-14) CMOS op-amp with 6.5 MHz GBW and rail-to-rail output — it is not a pin-compatible or functional drop-in for the DIP-8 TLC27L2CP. A board spin and different supply rail analysis would be required.
