Each channel can source or sink 30 mA, adequate for driving moderate loads like ADC inputs or a headphone buffer. The 1.9 mA total quiescent current (both channels) keeps the power budget modest — about 6.3 mW at 3.3 V, 30 mW at 16 V. This limits deployment to temperature-controlled environments: lab instruments, office peripherals, consumer audio, test equipment, and similar indoor gear. It is not qualified for automotive under-hood, outdoor telecom cabinets, or industrial motor drives where ambient temperatures routinely exceed 70°C or drop below freezing. If your application needs extended temperature, look at the TLC277's industrial-grade siblings (e.g., TLC277IP, -40°C to 85°C) or the surface-mount TLV series alternatives. ## 8-DIP through-hole — prototyping ease vs. production density The 8-pin DIP package (0.300\" row spacing, 7.62 mm body width) is a through-hole format. It is straightforward to hand-solder, socket, and rework — a clear advantage for breadboard prototyping, one-off builds, and legacy board repairs. In volume production, however, through-hole adds insertion cost and consumes more board area than a surface-mount SOIC-8 or MSOP-8. If your BOM targets automated assembly or high density, the TLC277 is also available in SOIC-8 (TLC277CD) and other SMD variants. The part is RoHS3 compliant (lead-free) and remains in regular production. For dual-sourcing or a surface-mount alternative, the TLV9352 (10.6 MHz, rail-to-rail output) or OPA4374 (6.5 MHz, quad channel) are functional peers in different package and performance tiers — but neither is a direct pin-for-pin drop-in for the DIP footprint.","metaTitle":"Texas Instruments TLC277CP LinCMOS Dual Op-Amp, 2.2 MHz","metaDescription":"TI TLC277CP dual CMOS op-amp in 8-DIP: 2.2 MHz GBW, 5.3 V/µs slew rate, 0.7 pA bias current, 3–16 V supply.

The TLC277CP offers a 2.2 MHz GBW and 5.3 V/µs slew rate versus the TL082's 3 MHz and 13 V/µs — the TL082 is faster for large-signal applications. The TLC277CP's key advantage is its 0.7 pA input bias current, orders of magnitude lower than the TL082's 50 pA typical, making it the better choice for high-impedance sensor interfaces.
