350 kHz GBW at 20 µA — the battery-life tradeoff
Each amplifier draws 20 µA quiescent current while delivering 350 kHz gain-bandwidth product and a 0.17 V/µs slew rate — a deliberate tradeoff that prioritises battery life over signal bandwidth. Rail-to-rail output swing lets it drive ADC inputs or signal lines directly from a 2.3 V minimum supply up to 5.5 V maximum, covering single Li-ion through 5 V regulated rails. The 0.5 pA input bias current suits high-impedance sensor interfaces — photodiode amplifiers, pH probes, or piezoelectric sensors — where bias current error would otherwise swamp the signal. Output drive is rated 17 mA per channel, enough to swing a 10 kΩ load rail-to-rail at 5 V.
Most op-amps in the 20 µA supply class top out at 85°C or 105°C. The 2 mV input offset voltage is typical for this class — not a precision instrumentation amp, but adequate for general-purpose signal conditioning in harsh environments.
Dual-channel in SOIC-8 — board-area efficiency
Two amplifiers in a single 8-pin SOIC (3.90 mm body width) saves board area versus two SOT-23 or SC-70 single-channel parts. No exposed thermal pad — the 17 mA output per channel keeps self-heating low enough that the standard SOIC-8 package handles dissipation without special layout treatment.
