Low-power dual op-amp for battery and industrial signal chains
The TLV27L2ID: Rail-to-rail output swing lets it drive ADC inputs or low-side loads without an extra rail. The 1 pA input bias current suits high-impedance sources like photodiode or pH sensor front-ends.
With a 160 kHz gain-bandwidth product, the TLV27L2ID is not a high-speed amplifier. It is sized for low-frequency conditioning: anti-aliasing filters below 10 kHz, temperature sensor buffering, or strain-gauge amplification where the bandwidth is a few hundred hertz. The 0.06 V/µs slew rate limits large-signal response to roughly 10 kHz at 2 V p-p, which is fine for slow-moving transducer outputs but not for audio line-level or switching waveforms.
7 µA per channel — the power-budget decision
The 7 µA supply current per channel is the headline feature. For a two-channel device, total quiescent draw is 14 µA typical. That puts it in the micropower class, competing with parts like the TLV2372 at 550 µA or the OPA2333 at 17 µA. If your BOM has a strict current ceiling — a 4-20 mA loop transmitter, a coin-cell-powered data logger, or an always-on sensor node — this part keeps the analog front-end draw negligible.
The full industrial temperature range extends to 125°C, covering under-hood automotive, engine-bay sensors, industrial oven controls, and outdoor telecom cabinets. The 2.7 V minimum supply lets it run from a 3.0 V lithium cell or a 3.3 V rail with headroom. At 125°C, input offset voltage (500 µV max) may drift, but the 1 pA bias current stays low enough for megohm-source impedances.
Package and supply reality
The TLV27L2ID ships in a standard SOIC-8 narrow body (3.90 mm width). The output is rail-to-rail, but the input common-mode range does not extend to the positive rail — typical for this class.
Lifecycle and sourcing
The standard SOIC-8 package and active status mean no unusual supply risk for production builds.
