0.4 µV offset — the dc precision anchor
That combination — sub-microvolt offset with MHz-class bandwidth — is what makes it useful for precision sensor interfaces, bridge amplifiers, and medical instrumentation where you cannot afford to trim or calibrate every board. The zero-drift architecture continuously corrects its own offset, so the 0.4 µV figure holds across temperature and over time, not just at 25°C.
Input bias current is 25 pA, negligible for high-impedance sources like pH probes or photodiode amplifiers.
Output drive and slew rate
Slew rate is 2.6 V/µs, which with the 5 MHz GBW gives about 80 kHz full-power bandwidth — fine for audio-frequency signal chains and control loops, not for video or high-speed data acquisition. Supply current is 1.1 mA per amplifier, a reasonable trade-off for the precision on offer.
Supplied in SC-74A / SOT-753 (SOT-23-5) — a five-pin surface-mount package with 0.95 mm pitch. Standard MSL 1 floor life, no bake required before reflow if the bag seal is intact.
Lifecycle — active, no LTB shadow
TI lists the LMP2021MFX/NOPB as Active.
